If a resistor of 15 Ω carries a current of 2.5 A for 12 seconds, the heat produced is _____
joules.
-
A.
450
-
B.
1800
-
C.
1125
-
D.
900
Correct Answer:
C. 1125
Explanation:
The heat generated in a resistor is determined by Joule's law of heating, which states that heat equals the square of the current multiplied by the resistance and the duration. By multiplying the square of 2.5 A (6.25) by 15 ohms and 12 seconds, the total thermal energy produced is 1125 joules.
