Question

What is the power of a lightbulb that has a current of 0.480 A at 120.0 V?

Answer 1

The power is 57.6 watts

Step-by-step explanation:

We can use the Electric Power Equation to evaluate the power.

Electric Power Equation

`P=IV`

`P` is the power in watts

`I` is the current in amps

`V` is the voltage in volts

Our lightbulb has current of 0.480 A and a voltage of 120.0 V.

`I=0.480\\V=120.0`

Now we can evaluate power.

Substitute our values in for the variables.

`P=0.480*120`

`P=57.6`
