Question

The power in an electrical circuit is given by the equation P = I2R, where I is the current flowing through the circuit and R is the resistance of the circuit. What is the current in a circuit that has a resistance of 100 ohms and a power of 15 watts? A.0.15 amps B.0.39 amps C.2.6 amps D.6.7 amps

Answer 1

Answer: 0.39

Step-by-step explanation:

15 = I^2 * 100

15/100 = I^2

0.39 = I

Answer 2

P = I²R
I = √(P/R)

P = 15
R = 100

Solve for I.
