Question

Why is half of the energy lost in charging a capacitor?

Answer 1

The problem of the "energystored on a capacitor" is a classic one because it has some counterintuitive elements. ... Buthalf of that energy is dissipated in heat in the resistance of thecharging pathway, and only QVb/2 is finally stored on the capacitorat equilibrium.

1. The problem of the "energy stored on a capacitor" is a classic one because it has some counterintuitive elements.
2. the battery puts out energy QVb in the process of charging the capacitor to equilibrium at battery voltage Vb.
3. The counter-intuitive part starts when you say "That's too much loss to tolerate.
