If we have a circuit with a x Ohm resistor and a 12 volt battery, what is the current?
What is the resistance of circuit with a voltage of 6.0 volts and a current of x amps?
An electrical device is rated at x watts.  Assuming that your deviceis plugged into a 115-volt outlet, how much current will flow through the device at full power?
