Question

How much electrical energy is used by a 75 W laptop that is operating for 12

minutes?
O A. 27,000 J
B. 108,000 J
C. 900 J
O D. 54,000 J

Answer 1

54,000 J

Step-by-step explanation:

Given,

Power ( P ) = 75 W

Time ( t ) = 12 minutes

To find : Electrical energy ( E ) = ?

t = 12 minutes

= 12 x 60

t = 720 seconds

Formula : -

E = Pt

E = 75 x 720

E = 54,000 J

Therefore,

54,000 J is the electrical energy is used by a 75 W laptop that is operating for 12 minutes.
