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