Two capacitors with capacitances of 1.5 $\mu$F and 0.25 $\mu$F, respectively, are connected in parallel. The system is connected to a 100-V battery. What electrical potential energy is stored in the 1.5-$\mu$F capacitor?

Question

Quizplus · Accepted Answer

The energy stored in a capacitor is given by the formula $ E = \frac{1}{2} C V^2 $. For the 1.5 μF capacitor connected to a 100 V battery, $ E = \frac{1}{2} \times 1.5 \times 10^{-6} \times (100)^2 = 7.5 \times 10^{-3} $ J.
