Physics - Capacitor Question with Solution | TestHub

Key Idea Potential drop is zero along an ideal conductor because it has zero resistance. Potential at point $\mathrm{A}=10\mathrm{V}$ Potential at point $\mathrm{B}=0\mathrm{V}$ $\therefore$ Potential difference across $\mathrm{AB}=10\mathrm{V}$$\begin{array}{rl}\text{ Heat produced }& =\text{ Energy stored }=\frac{1}{2}{\mathrm{CV}}^2\\ & =\frac{1}{2}\times 10^{-6}\times (10{)}^2=50\mu \mathrm{J}\end{array}$
