How do batteries work? On a battery, there is a positive end and a negative end. Electric current runs from the negative side and into the negative side. The potential that is created through the wiring causes anything connected to a battery run. Using a battery and some open wiring, we were able to light up a small light bulb. One way that worked is by putting one end of the open wire on the negative side of the battery and connecting it to the positive side where there was also a light bulb. When connected, the light bulb lit up.
Below are some quick videos of electric fences which represented the different amounts of electric potential at different heights.
Using Logger Pro, Professor Mason was able to measure the different currents that ran through the wires.
Below is his set up of circuits. The red box is an older version of a voltmeter, which measures the voltage running through a circuit.
