Question

A light draws 220 watts on a 120 volt circuit, how many amperes of electricity is it using?

Answer 1

Answer:

The correct solution is "1.83 A".

Explanation:

The given values are:

Power,

P = 220 watts

Current,

I = 120 volt

Now,

The voltage will be:

⇒  $P=I\times V$

or,

⇒  $V=\frac{P}{I}$

On substituting the values, we get

⇒      $=\frac{220}{120}$

⇒      $=1.83 \ A$
