Question #121177

How much energy is transferred when a current of 3 A flows in a circuit with a voltage fo 12 V in 1 minute?

Expert's answer

The power, delivered to the circuit is the following:

"P = IU = 3A\\cdot 12V = 36W"

The energy during 1 min will be:

"Q = Pt = 36W\\cdot 1min = 36W\\cdot60s = 2160J"

Answer. Q = 2160J.
