I. Introduction
In today’s society, the need to have an adequate supply of electricity to run everyday tasks is in greater demand than ever. Everyday we turn our lights in our homes on and off without really thinking about if there is enough electricity to power each and every light. Throughout this paper, we examine Kirchhoff’s Voltage Law the sum of the electrical potential differences around any closed network is zero [1]. Represented by the equation ΣV=0, which means v1+ v2+ v3+…+ vn=0 [2]. A way at looking at this equation in words is by the sum of the voltage rises in the loop will equal the sum of voltage drops in the loop [2]. By applying this principle electrical engineers can use this to determine if there is enough energy to power an entire circuit ranging from small items like a flashlight, to skyscrapers in the world’s largest cities.
II. Procedure
Three experiments were performed in order to prove Kirchhoff’s Voltage Law. The first experiment performed would verify that the voltage across a straight path would add up to the same voltage summed from the voltage sources. The second experiment performed would be to verify that voltage across multiple paths would add up to the voltage of the voltage source. The third experiment performed would be to verify that both of the ideas expressed in experiment one and experiment two would remain consistent together.
All of the experiments we performed utilized a voltmeter, a breadboard, some wire, two different types of voltage sources, and resistors with a range of resistance. All components were plugged into the breadboard for ease of testing purposes using the voltmeter.
For experiment one, a continuous loop was made on the bread board using a 9 volt (v) bat...

...al zero; known as Kirchhoff’s Voltage Law. With the three trials conducted we were able to provide evidence to prove that the sum will in fact equal zero. Kirchhoff’s Voltage Law is a very important tool engineers can use to determine whether or not there is enough voltage in a closed circuit to carry a current through the world’s tallest skyscrapers so the entire building can be with electricity.

The first method of insuring a correct reading is obtained is through using one wattmeter on a balanced load. Using this on an unbalanced load will lead to an inaccurate reading for power. To complete this method a reading with a wattmeter connected from a single line to neutral via the voltage probes and in line with the line on the current probes. By multiplying the value of the wattmeter by three the total system power is found.
...ending on the size and tolerances of the patients, the voltages could have ranged anywhere form 70 to 130 volts. As a direct effect from the large amounts of electricity being imposed into the patient’s body they will lose consciousness almost immediately. The shocks sent them in to convulsions or seizures and therefore increased their insulin levels. After a patient regains consciousness, he or she will not remember any of the events of being shocked.

One thunderous afternoon on June 1752, Benjamin Franklin conducted what is known today as the “Kite Experiment”. He wanted to prove that if one object was electrical, the energy from that object could be transferred to another object, therefore being classified as electricity and lightning. With his son William, Ben took a string and attached the kite to it, then he attached an iron key to the kite. Next, they tied a thin metal wire from the key and put the wire inside a Leyden jar which stored all the electrical charge. His experiment profitably showed that his accusations were correct. Many other scientist tried the same experiment and were electrocuted, but Ben Franklin was the lucky one. He changed the world of science.
The chemical reaction between 2 different metals and the juices in the potato generate enough voltage to actually make a clock run or a light bulb a small one. The whole experiment should produce about 1.5 volts DC. You might need to use more than one potato but one should power a small light bulb. It works because the phosphoric acid (H3PO4) in the potato. The potato acts more as an electrolyte not really having a role in the chemical reaction itself.
In this case, the circuit will be analysed using a standardized Mesh Analysis using Kirchhoff’s Voltage Law. Indicated in the Figure 1 below are the loop directions (estimated) and the points for analysis of current and voltage have a sun shape about them.

The only problem with this experiment is that when the current passing through the battery circuit was at a continual rate there was...
Do you ever wonder about what happens with electricity? In the article “Energy Story” written it tells you about atoms and what things need to have to be that type of object. In the article “Conducting Solutions” by Rodney Schreiner tells you about solutions and the reactions to them with electricity. In the video clip “Hands-on Science with Squishy Circuits” by AnnMarie Thomas it tells you about how simple play dough can hold electricity.
In this paper, I will talk about how AC circuits can be described by considering voltage and current using complex numbers. An AC circuit requires two separate numbers to be able to completely describe it. This is because it takes into account the amplitude and the phase of the current. The fact that complex numbers can be easily added, subtracted, multiplied or divided with each other makes them ideal for this operation where both amplitude and phase have to work together.
F. A large coil surrounding an iron rod is given a constant current. A copper coil is placed over the rod, but is not a complete loop. The coil is then closed to complete the loop.
Copper wire, bare, 24-gauge, 9 V battery, 9 V battery clip, and more. I am going test each liquid to see which liquid has more electrolytes, and by knowing that it will help me find out which is better for you. I believe by doing this experiment it will help me see if my hypothesis is right or
You take voltage measurements by counting the number of divisions a waveform spans on the oscilloscope's vertical scale. Adjusting the signal to cover most of the screen vertically, then taking the measurement along the centre vertical graticule line having the smaller divisions makes for the best voltage measurements. The more screen area you use, the more accurately you can read from the screen.
In the experiment there are several possible ways of changing the electric current such as changing the voltage or the position of the electrodes within the electrolysis cell. However, it was found from preliminary work that the most effective way to change the current was to change the concentration of the acid solution. The preliminary work showed that the greater the concentration of the acid, the greater the current. Ohm's law states that R(resistance) =
Humans these days take electricity for granted. We don’t truly understand what life was like without it. Most young adults will tell you their life does not depend on electricity, but they aren’t fooling anyone. They all know that their life depends on electricity; whether it’s television, their phone, Google, or the lights in their house. We need to stop taking those things for granted and give credit where credit is due. That is why I chose to write about the scientists who contributed to the discovery of electricity, which then helped modern scientists fuel the electricity phenomenons we now have today.
Coulomb's work would become one of the first cases where electric charge was measured quantitatively. In the 1740's electricity was beginning to become well know. By the 1750's, Benjamin Franklin's had shown that lightning was an electrical phenomenon thereby proving that that electricity did exist in nature. Franklin's work became an inspiration to others and spawned research into the study of electricity and measurement of it.
