scientists first began, they thought that positive energy flowed first. Today, it is a common theory that electricity works best using the conventional current because it flows positive to negative. You said in class that electricity flows through circuits and works like water. The...
Resistors in Series and in Parallel I. OBJECTIVE The objective of the study is to understand and differentiate the resistance, voltage, and the current relations in circuits in series and in parallel II. THEORY Series circuits A series circuit is a circuit in which resistors are arranged in a chain, so the current has only one path to take. The current is the same through each resistor. The total resistance of the circuit is found by simply adding up the resistance values of the individual

To people who don’t understand, Youtube can be a waste of time but to me, it is a door of possibility. It lead me to think creatively on my own. It also inspired me to come up with dreams and goals that I did not think of before. Technology has always been a vital essential to my life. Youtube has shown me that with technology I can bring my ideas to fruition. After extracting what I learned from Youtube, it encouraged me to participate in an engineering program, and with the knowledge I gained I
Circuit Analysis Lesson Plan: What is a Circuit? Before we can properly analyse a circuit, we must first understand what a circuit is. A circuit is a closed loop that allows charges to move continuously. There are two requirements that must be met in order to create a circuit: it must be a closed loop with conductive wires connecting to both the positive terminal and negative terminal of the cell, and there must be a source of energy that can increase the electrical potential energy of the charge
inverter intended to obtain better efficiency by maintaining the constant low voltage. Keywords—parallel resonant inverter, Resonating components, High frequency transformer, Leakage inductance, Transfer Function. I.INTRODUCTION Advent of devices with better switching capabilities has enriched the field of power electronics. This enables the development of converter circuits with improved and high performance[6]. The AC-DC
Inversion is the change of dc power to ac power at a desired output voltage or current and frequency. A static semiconductor inverter circuit does this electrical energy inverting transformation. The terms voltage-fed and current-fed are used in relation with the output from inverter circuits. Conventionally, inverters are classified into two broad categories – voltage source inverter (VSI) and current source inverter (CSI). A VSI is one in which the dc input voltage would have to keep constant and
almost constant turns out to be an important characteristic of the zener diode as it can be used in the simplest types of voltage regulator applications. The function of a regulator is to provide a constant output voltage to a load connected in parallel with it in spite of the ripples in the supply voltage or the variation in the load current and the zener diode will continue to regulate the voltage until the diodes current falls below the minimum IZ(min) value in the reverse breakdown region.
the other side of the world and a host of other applications. These have become possible largely because we have learned how to build complete circuits, containing thousands of electronic parts, on a tiny wafer of silicon no more than 5mm square and 0.5 mm thick. Microelectronics is concerned with these ‘densely populated’, miniaturized integrated circuits (ICS), or ‘chips’ as they are called, which are changing the way we live and work and challenging us to see that the changes are for the better
The output of temperature sensor is smaller in amplitude as well as low signal power so amplifier is used to amplify weak signal. We have used here LM35 series temperature sensor. LM35 series sensor is an integrated circuit whose output is linearly proportional to centigrade or Celsius temperature. Because of we get directly output of LM35 series sensor in centigrade it becomes its advantage as compared to linear temperature
on in the circuit that was given to me. I will explain with the best of my knowledge so that you can fully understand what is happening in the circuit. The inductor and the wires are assumed as being ideal. The AC voltage source has an infinitely variable frequency (0≤f≤∞). The values of all the resistors, capacitor, and inductor are constant. In this AC circuit, you can analyze that each resistor is in series with either an inductor, voltage source, or capacitor. Resistor 2 is in series with the
1. INTRODUCTION Today, thanks to the advancement in the field of electronics, most of the manually controlled systems are getting replaced with sophisticated electronic circuits with intelligent controlls. These circuits are capable of monitoring, analyzing and controlling the systems. In earlier days these electronic circuits were fabricated around discrete hardware components such as transistors, logic ICs etc that made the system bulky and costly. Also since the component count was more the failure

This helped broaden my knowledge with electrical circuits and stimulated creativity that will in turn enhance my knowledge with the physical
In this section, The basics of electromagnetic transients, HV Capacitors banks and their relations and functions in the power system are presented. Electromagnetic Transients (EMT) Electromagnetic transient (EMT) phenomena occurs in the power system when the network changes from one steady state into another which creates a disturbance in the power system that involve destructive high magnitudes of current and voltage or even both, as per (ANSI std. 1100-1992) the EMT is defined as “a sub-cycle

In general batteries are into two categories. Primary batteries are non-rechargeable and are commonly found in consumer electronic products. Common primary batteries include zinc-carbon, zinc-alkaline-MnO2, zinc-air, and lithium batteries. Secondary batteries are distinguished by their ability to recharge. Examples include lead-acid, Nickel-Cadmium (NiCad), Nickel-Metal Hydride (NiMH), and Lithium-ion (Li-ion) batteries. For vehicular applications, secondary batteries are the preferred for power
Capacitor Investigation Report Aim: the aim of this investigation is to study capacitors charging and discharging. A capacitor is charged by placing it in a circuit with a resistor and a power source. When electrons flow round the circuit they can not cross the gap the capacator makes. A negative charge builds up on this side of the capacitor whilst on the other a positive charge because of this. A potential difference across the gap now occurs causing the charging to slow down. When
Receiver being adjusted. I will begin by discussing the first capacitor. This capacitor is connected in parallel with an inductor. While the capacitance changes as the dial is turned, the resonant frequency of the LC circuit also changes. This process is called inductor and capacitor in parallel. When the capacitor is in just the right spot, the resonant frequency will be 1290 KHz. This LC circuit is designed so that only the resonant frequency is passed. The 1290 KHz will now be passed on to the next
