What is the power delivered to a light bulb when the circuit has a voltage drop of 120 V and produces a current of 15.0 ampere?

Question

Group of answer choices

1,800 watts

0.125 watts

8 watts

1,200 watts

Answer 1

To find the power delivered to the light bulb, you can use the formula for electrical power:

\[ P = V \times I \]

where:

• \( P \) is the power in watts,
• \( V \) is the voltage in volts (120 V in this case),
• \( I \) is the current in amperes (15.0 A in this case).

Plugging the values into the formula:

\[ P = 120 , \text{V} \times 15.0 , \text{A} \] \[ P = 1,800 , \text{watts} \]

Thus, the power delivered to the light bulb is 1,800 watts.
