What is the voltage of a circuit that has a current of 0.5 amps and a resistance of 110 ohms?

Assuming this is a DC circuit, use Ohm's Law to find the answer.

Ohm's Law states E = I x R (Voltage = Current x Resistance)

E = 0.5a x 110 ohms

E = 55 volts

A/C requires a more complicated formula and more information in the given question.
