A resistor connected to a 12V battery draws a current of 2A. The energy dispatched in the resistor in 5 minutes is ___.
-
A.
3,600J -
B.
6,000J -
C.
7,200J -
D.
14,400J
Correct Answer: Option C
Explanation
Power drawn by the resistor = IV = (2)(3) = 24W = 24J/s
Energy dissipated = power × time = (24)(5)(60) = 7200J
