Question

A capacitor of capacitance $10\mu F$ is connected to a battery providing a potential difference of 10 V across the capacitor. The energy stored inside the capacitor is?

• A. $100\mu J$
• B. $500\mu J$
• C. $1mJ$
• D. $5mJ$

Answer 1

The correct option is B $500\mu J$

$E=\frac{1}{2}C{V}^{2}E=\frac{1}{2}10\times {10}^{-6}\times 100E=5\times {10}^{-4}J$
