Ohm’s Law Experiment V A E B C A + + S Resistance Wire − Power Supply • For this experiment – Current controls need to be turned completely counterclockwise -- we will later adjust the current to 1A. – Voltage controls completely clockwise Notice that there is a coarse and fine adjustment for both current and voltage. • When the green power button is pushed in, the power supply is on. When it is out, the power is off. • You will use the + and − terminals to complete the circuit just like you would for a battery. • To connect the circuit, first put the items in the circuit on the table in a position similar to that in the diagram. This is not necessary but it makes it easier. V A E B C A + + S Resistance Wire − The red wire is connecting the positive terminal of the power supply to point A, the end of the resistance wire. The resistance wire lays on top of the meter stick V A E B C A + + S Resistance Wire − The blue wire is connecting the point A, the end of the resistance wire to the voltmeter. One banana plug can attach to the other banana plug at point A. A E B C A + + S Resistance Wire − V A E B C A + + S Resistance Wire − V A blue wire was then connected from the switch to the negative terminal of the power supply. This completed the circuit. Yes. When the switch is connected in this manner it will complete the circuit. No. This will not work. Why? Please note that the colors of the wires is not important. Different color wires were used in these pictures to help illustrate how to wire the circuit. Notice that wiring is simply a matter of following the circuit diagram. Pick a starting point and go from one point to the next. Placing the items to wire in a position similar to the diagram makes this easy. A E B C A + + S Resistance Wire − V
