A capacitor of 10µF is connected across a cell of 12 volts as shown above, calculate the energy stored in the capacitor

Answer Details

The energy stored in a capacitor is given by the formula: E = 1/2 * C * V^2 where E is the energy stored, C is the capacitance and V is the voltage across the capacitor. From the given information, the capacitance is 10µF and the voltage across the capacitor is 12V. Substituting these values in the formula, we get: E = 1/2 * 10µF * (12V)^2 E = 1/2 * 10^-5F * 144V^2 E = 7.2 x 10^-4 J Therefore, the energy stored in the capacitor is 7.2 x 10^-4 J. The option closest to this value is 7.2 x 10-4J.
