the current flowing through the circuit and Ris the resistance of the circuit.
What is the current in a circuit that has a resistance of 30 ohms and a power
of 2 watts?
A. 15 amps
B. 0.26 amps
C. 3.9 amps
D. 0.067 amps

Answer:

B

Explanation:

P = I² R

If P is 2 watts and R is 30 ohms:

2 = I² (30)

I = √(1/15)

I ≈ 0.26 A

Answer:

B. 0.26 amps is your answer
