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

Answer:

0.5 Amperes

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):

$I=\frac{P}{V}$

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:

$I=\frac{60W}{120V}\\ I=0.5A$

the Current running into the bulb is 0.5 Amperes
