Capacitor and battery loss
Energy dissipated across a resistor when charging a capacitor
When a capacitor is charged from zero to some final voltage by the use of a voltage source, the above energy loss occurs in the resistive part of the circuit, and for this reason the voltage source then has to provide both the energy finally stored in the capacitor
