An electric iron operates on a 120-volt outlet and uses 2.30 amps of current. How much power does the iron use?

A. 0.019 watts

B. 276 watts

C. 52 watts

D. 630 watts

There are a few different formulas for electrical power. They involve

different combinations of voltage, current, and resistance.

==> Power = (current) ² x (resistance)

==> Power = (voltage) ² / (resistance)

==> Power = (voltage) x (current).

In this case right now, we know the voltage and current, so maybe

it's a good idea to use the formula that involves voltage and current.

Power = (voltage) x (current)

= (120 volts) x (2.3 Amperes)

= 276 watts.
