Answer to Question #121177 in Physics for Maria

Question

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

Answer 1

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.
