Question

isa Honda pulls into the garage and turns off her car. She flips on the car's inside overhead lights so she can gather her belongings. The car's battery impresses 12 Volts across the light and the current in the light is 0.386 Amps. What is the power rating of the light bulb?

Answer 1

The power rating of the light bulb is 4.632 Watts.

Step-by-step explanation:

To calculate the power rating of the light bulb, we use the formula:

Power (P) = Voltage (V) × Current (I)

Given that the voltage across the light bulb is 12 Volts and the current through the light bulb is 0.386 Amps, we can substitute these values into the formula to find:

Power = 12 V × 0.386 A = 4.632 Watts

Therefore, the power rating of the light bulb is 4.632 Watts.
