Question

What is the rms current flowing through a light bulb that uses an average power of 60.0 W when it is plugged into a wall receptacle supplying an rms voltage of 120.0 V?

Answer 1

I = 0.5 A

Step-by-step explanation:

Given that,

Average power of a light bulb, P = 60 W

The rms voltage supplied is 120 V

We need to find the value of rms current flowing through the light bulb. The relation between the power, voltage and current is given by :

P = VI

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

So, the rms value of current is 0.5 A.
