    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
