Question

A light bulb has a power rating of 60 W. What is the current running into it if it is plugged into a 120 V outlet?

Answer 1

0.5 Amperes

Step-by-step explanation:

Information that we have:

Power:
`P=60W`

Voltage:
`V=120V`

and we use the equation that relates this two quantities to the Current (I):

`I=(P)/(V)`

where I is the curent, P is the Power and V is the Voltage.

we substitute the values given for the Power and the Voltage to find the current:

`I=(60W)/(120V)\\ I=0.5A`

the Current running into the bulb is 0.5 Amperes
