Question

a portable cd player uses a current of 7.5 ma at a potentioal difference of 3.5 how much energy does the player use in 35 s

Answer 1

Answer:0.91875j

Step-by-step explanation:

use the equation

power= current * voltage

power= 0.0075A*3.5v

and then multiply it by 35 since you want to get the total power for the 35 seconds.

0.0075A*3.5v * 35s = 0.91875j
