Question

You have a nightlight plugged into an outlet in the hallway, which uses 3.5 watts when plugged in. If the house circuit provides 120.0 volts, wh

is the current through this bulb?

A. 420 amps

B.

0.029 amps

C.

34 amps

D.

0.0083 amps

Answer 1

I = 0.029 A

Step-by-step explanation:

Answer 2

I = 0.029 A

Step-by-step explanation:

It is given that,

Power of hallway is 3.5 watts

The house circuit provides 120 volts

We need to find the current through this bulb. The power of electric bulb is given by :

`P=VI`

`I=(P)/(V)\\\\I=(3.5)/(120)\\\\I=0.029\ A`

So, the electric current is 0.029 A.
