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 and also the energy lost by dissipation during the charging process.
