Question

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

Answer 1

the answer is b for plato users

Step-by-step explanation:

Answer 2

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 .
