Weegy: To find the voltage in a circuit when given the resistance and the current, we apply the first listed expression:
E = I x R, and inserting our known variables, we have E = 20 amps x 12 ohms = 240 volts. [ A circuit with a resistance of 12 ohms and a current of 20 amps has 240 volts applied to it.
The answer is: 240 volts. ] (More)
