Consider a simple circuit where resistance R is connected in series with a capacitor C and a voltage source V. The switch is connected at t=0. After t>>RC, the capacitor is fully charged with energy Es=1/2*CV^2 and R dissipates energy of Ed=1/2*CV^2. Question. 1) How can one design a circuit to reduce energy dissipated by R? 2) How can one design a source V(t) such that it can charge the capacitor to Es with Ed<Es.
