Answer:
54,000 J
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.
