The INCORRECT formula representing the energy stored in a parallel plate capacitor in usual notation is
The INCORRECT formula representing the energy stored in a parallel plate capacitor in usual notation is
Show Hint
Physics Tip: Always check units. Energy must have unit Joule. If an expression gives Farad, Volt, or Coulomb only, it cannot represent stored energy.
