The power in an electrical circuit is given by the equation p=/2 R, where /is the current flowing through the circuit and R is the resistance of the circuit. what is the power in a circuit that has a current of 12 A. 120 watts
B. 8.3 watts
C.144 watts
D. 14,400 watts

Complete Question:

What is the power in a circuit that has a current of 12 amps and a resistance of 100 ohms?

D. 14,400 watts

Explanation:

The electrical power of an electric circuit can be defined as a measure of the rate at which energy is either produced or absorbed in the circuit.

Mathematically, electrical power is given by the formula;

This ultimately implies that, the quantity (current times voltage ) is electrical power and it is measured (S.I units) in Watt (W).

Given the following data;

To find the power in the circuit, we would use the following formula;

Power = I²R

Where;

Power = 12² * 100

Power = 144 * 100

Power = 144,000 Watts

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
