What is the voltage in a circuit that has a current of 10.0 amps and a resistance of 28.5 ohms?

A. 2.85 volts

B. 285 volts

C. 0.35 volts

D. 18.5 volts

V = I · R = (10 A) · (28.5 Ω) = 285 volts.

Ohm's law deals with the relation between voltage and current in an ideal conductor. It states that: Potential difference across a conductor is proportional to the current that pass through it. It is expressed as V=IR.

V = 10.0 A (28.5 ohms) = 285 V
