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?

120v × .75a = 90wSource(s): Been there

watts is volts times amps
so we get 120 x 0.75 you do the math

You really need to read that chapter in the textbook.

W = 120V*0.75A = 90 WATTS
HOWEVER, 90W LIGHT BULB WAS NOT EXISTED IN MARKET ! SOME THING WENT WRONG FROM YOUR SCIENCE FAIR MATERIAL !!!

It’s just watt = voltage * ampere
120 * 3/4 = 90 W

P = EI = 120 x 0.75 = 90 watts
