SUMMARY
The energy dissipated by a 25 ohm resistor in a circuit with a 0.25 µF capacitor charged to 50 V is calculated using the formula for energy stored in a capacitor, which is (1/2)CV². Initially, the energy stored is (1/2)(0.25 x 10^-6 F)(50 V)², resulting in 0.000625 Joules. Upon complete discharge, all this energy is dissipated through the resistors in the circuit, confirming that the 25 ohm resistor dissipates the same amount of energy as the capacitor initially stored.
