Question

A lightbulb has a voltage of 120 V and uses a current of .75 amps. What is the electric power used by the lightbulb? Show work

Answer 1

G: V=120v and I=.75amps
U: R=?
S: To fins the resistance of the lightbulb you’d have V divided into I so,
S: 120/.75 = Therefore the resistance is 160ohm

Answer 2

Answer:90watts

Step-by-step explanation:

power= current X voltage

P=IV

Where

I=current

V=voltage

P=power

P=0.75 x 120

P=90Watts
