Ohm's Law (5F10.10)

Description:

Uses the Resistance Wires (5D10.20) board described above, but in this demo the voltage is also varied.

Procedure or Operation Notes:

Pick one of the Resistance Wires on the board. Connect one, two, or three battery cells to the wire.

Using wire C (resistance = 30Ω):

One cell. Voltage = 4.2V. Current = 0.14A.

Two cells. Voltage = 8.3V. Current = 0.28A.

Three cells. Voltage = 12.3V. Current = 0.42A.
