Introduction to Capacitors, Capacitance and Charge

Also, because capacitors store the energy of the electrons in the form of an electrical charge on the plates the larger the plates and/or smaller their separation the greater will be the charge that the capacitor holds for any given voltage across its plates. In other words, larger plates, smaller distance, more capacitance.

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.
