Question

7th grade science urgent! begging for help! if you have a voltage of 120 volts entering your house and a lightbulb with 0.75 amperes flowing through it, how many watts is ur light bulb?

Answer 1

Answer:

90 W

Explanation:

The power of the light bulb is given by:

$P=VI$

where

V is the voltage of the bulb

I is the current through the bulb

In this problem,

V = 120 V

I = 0.75 A

Substituting into the equation,

$P=(120)(0.75)=90 W$
