Andre Marie Ampere was a French Physicist who had many great discoveries throughout his life. He was born on January 22, 1775 in Lyon, France. Ampere created electromagnetism, which started the science of electrodynamics. With this discovery the unit measure of electromagnetism was named after ampere. Ampere was born into a very financially set middle class family. Andre’s mother was a devout woman (Shank). She was a charitable and very religious (Fox). His father (Jean Jacques Ampere) was a successful

How the Resistance of a Filament Bulb Varies Its Current Flowing through It Aim: the purpose of this investigation is to find out how the resistance of a filament bulb varies with current flowing through it. Hypothesis: I think the higher the voltage the brighter the bulb will be because then there will be an increase of current and the electrons are given more energy and more are forced through, therefore the bulb would be able to resist more. If the voltage increases the bulb will shine

also it can bear the inrush current without being damaged. 6.2. General Method Of Transformer Sizing: The general method of transformer sizing follows five basic steps that are: Collection of data about the source and the load. Determine the KVA, Amperes or wattage required by the load Calculate the transformer size based on inrush current Characterize the impedance of
get to the usual mathematical situation that identifies the relation: V=IR. A lot more particularly, 8 Ohms regulation states which the R in this relation will be steady, self-governing of current. The SI unit with regards to measuring a current is ampere that flows of electric charges by the way of exterior on the rate of merely one coulomb every second. Electric current can be calculated using an ammeter. The abbreviation of AC and DC are often used to mean simply alternating and direct current.
The History of Magnets and Electromagents Magnets and electromagnets have many uses, every electric motor, generator or transformer requires a magnetic field for it's operation. With the exception of a few special types, all use electromagnets. The magnets mounted on large cranes are used to lift heavy loads. Magnetism makes the generator supplying the electricity to your home work and the radio
Experiment 1 Aim: To test the influence that the potential difference will have on the current of an electric circuit. Investigative Question: What would the effect of the change in potential difference have on the current of the circuit, if the temperature in the circuit remains constant? Hypothesis: By decreasing the resistance in the electric circuit we will be increasing the total potential difference in the circuit and will therefore directly strengthen the current in the circuit. The relationship
concepts on which... ... middle of paper ... ... insight was pretty amazing considering the electron would not be discovered for another 75 years. Magnetic fields A magnetic field describes a volume of space where there is a change in energy.. As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit
Investigating the Resistance of a Wire The aim of this investigation is to see how the length of a wire affects its resistance. Background knowledge To make current flow through a conductor, there must be a potential difference (voltage) across it. As the current continues to flow there are certain factors which increase the resistance; Length of wire: as the length increases there will be a higher percentage of fixed atoms, therefore the electrons carrying the charge will collide
Cable Sizing and Selection Introduction: One of the important aspects of designing any electrical system is to select an appropriate type and size of a cable. Too much small size of cable generates a lot of heat in a cable which will caused permanent damage to an insulation of a cable and using a too much large cable size means we are wasting our money on copper because copper is the costly material for cables. So we must have to select a cable that is neither of too small nor too large size
battery by Volta, and the invention of Volta’s. Volta’s discoveries would lead the way for Ohm’s law several years later. However, before that discovery was made Hans Christian Ørstead discovered electromagnetism, which was then used by André Marie Amperè to show that magnetism is electricity. Following the publication of Ohm’s law, Faraday would publish his findings on induction in the 1830’s. That same decade the DC generator, and transformer were invented, and followed in the 1840’s by the invention
PTC Thermistors There are three types of PTC or positive temperature coefficient thermistors. • Ceramic Switching PTC Thermistors • Silistor Silicon PTC Thermistors • Polymer PPTC Thermistors Change in the resistance of a PTC thermistor can be brought about either by a change in the ambient temperature or internally by self-heating resulting from current flowing through the device. Manufacturing process The manufacturing process for PTC thermistors begins by mixing selected material with a binding
converters (DACs). FIGURE1.Analog to Digital converter In the analog to digital converter the input vary from minimum to maximum value of volts or amperes. The output is a digital number that represents the input value. In the digital to analog converter the input that specifies an output whose value changes in steps. These step changes are in volts or amperes. Analog to digital conversion techniques have become extremely important. In this a great deal of technical effort has gone to produce analog to
The Development of Wireless Communication Leading to the Alexanderson Alternator Not much has changed in human nature in the past couple centuries. When we want something, we desire exactly what we want without deviation and we wish to have it quickly. This is as evident in modern times as it was in the late nineteenth and early twentieth centuries. It is difficult to imagine for the modern man, but there was once a time when messages and information had to be delivered by hand, horseback or by
by magnetic forces, the experiment proved that an electric current produces magnetism. Research, p.2 Also, during the 1820’s, the French physicist Andre’ Marie Ampere declared that electric currents produce all magnetism. He concluded that a permanent bar magnet has tiny currents flowing in it. The work Oersted and Ampere did led to the development of the electromagnet—which is used in such devices as the telegraph and the electric bell. They confirmed as stated earlier: Most electromagnets
Circuits, what is up with that? First you need to understand how all the parts of a circuit relate. The main thing that a circuit has is conductance and that all the parts are conductors. Conductors are materials in which electric charges move freely. If the material isn't a conductor, it is either a insulator or a semiconductor. Conductors are mainly metalic substances such as copper, aluminum, and gold. Conductors allow a charge to build up and move "freely" through the conductor. When dealing
capacitors. Resistors are defined as-The impedance to the flow of electric current. The resistance is equal to the voltage across the object divided by the current through it. Measured in volts per ampere, or ohms.(Physics, A World View 513) Current is defined as-A flow of electric charge. Measured in amperes. (Physics, A World View 513) A combination of a resistor and capacitor in series or parallel is called a filter.
Factors that Affect the Resistance of Resistance Putty This investigation is designed to look into the resistance of different materials, in this case, resistance putty in the form of wires, and their conducting capability in different shapes. We must bear in mind though that different thickness and length of the putty used to make up the wire itself will affect the electric conduction capability. Therefore, the factors are; The thickness of the putty e.g. 1mm, 2mm, 3mm in diameter or 1
The theory behind gauss guns is that you can take electrical energy and convert it to kinetic energy by using an electromagnetic energy storage field. In essence, you take a ferrous object (the projectile) and place it at one end of a hollow solenoid. When electricity is applied to the coils inside the solenoid, a magnetic field is generated which pulls the projectile towards the center of the coils. As the projectile reaches the center and continues, the magnetic pull decreases and eventually
