Question

Suppose a motor connected to a 120 V source draws 10.0 A when it first starts. What is its resistance?

a) 12 Ω
b) 24 Ω
c) 10 Ω
d) 6 Ω

Answer 1

The resistance of a motor connected to a 120 V source and drawing 10.0 A is found to be 12 Ω using Ohm's Law.

Step-by-step explanation:

The resistane R of a motor when connected to a 120 V source and drawing 10.0 A can be calculated using Ohm's Law, which states V = I * R, where V is voltage, I is current, and R is resistance. Plugging in the values, we get:

R = V / I = 120 V / 10.0 A = 12 Ω.

The correct answer is (a) 12 Ω, which means the resistance of the motor when it first starts is 12 ohms.
