Question

Q1.A parallel plate capacitor is charged, such that electric field between the plates of capacitor is E. The energy density of the capacitor is​​​

Answer 1

$for \: a \: capacitor \: \\ \\ total \: energy \: = \: \frac{1}{2} {cv}^{2} = \: energy \\ \\ density \: \times volume \: \\ where \: c = \: e {}^{o} a \: by \: d \: \\ v = ed \\ u = ( \frac{1}{2} e \: o {e}^{2} ) \\ ad \: \\ \\ ans \:$
