Complete Question:
What is the power in a circuit that has a current of 12 amps and a resistance of 100 ohms?
Answer:
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;
[tex] Electrical \; power = current * voltage [/tex]
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;
- Current = 12 Amperes
- Resistance = 100 Ohms
To find the power in the circuit, we would use the following formula;
Power = I²R
Where;
- I is current measured in Amperes.
- R is resistance measured in Ohms.
Power = 12² * 100
Power = 144 * 100
Power = 144,000 Watts
