Question

The resistance of the wire is 100 Ω. If it is carrying a current of 1 A for 10 seconds, the heat produced will be _ _ _ _ _ _ .

• A. 10 J
• B. 10000 J
• C. 0.1 J
• D. 1000 J

Hint:

The formula for calculating heat produced by a resistor is H = I² × R × t, where I is current, R is resistance, and t is time.

Answer 1

The Correct Option is A

The heat produced in a resistor is given by the formula: H = I² × R × t where I is the current, R is the resistance, and t is the time. Given:
- I = 1 A
- R = 100 Ω
- t = 10 seconds
The heat produced is: H = (1)² × 100 × 10 = 1000 J. Thus, the heat produced is 1000 J, so the correct answer is (D). Final Answer: 1000 J.
