Question

How much current does a 75-W light bulb draw when connected to 120 V?

Answer 1

We will determine the current as follows:

First, we recall that:

`I=(P)/(V)`

So:

`I=(75W)/(120V)\Rightarrow I=(5)/(8)A\Rightarrow I=0.625A`

So, the current that a 75-W light bulb draws when connected to 120 V is 0.625 Amps.
