Given : a resistor of resistance 40 Ω produce 1000J of heat energy,
To Find : the potential difference between the two ends of the resistor
Solution:
Heat produced = V²/R
Heat produced = 1000 J
Resistance = 40 Ω
V²/40 = 1000
=> V² = 40 * 1000
=> V = 200 V
potential difference between the two of the resistor = 200V
