What is a charge of a capacitor?
The process of storing electrical energy in the form of electrostatic field when the capacitor is connected to a source of electrical energy is known as charging of capacitor. This stored energy in the electrostatic field can be delivered to the circuit at a later point of time.
When a capacitor is full of charge the current is highest?
The size of the current is always at a maximum immediately after the switch is closed in the charging or discharging circuit, because the charging current will be highest when the capacitor is empty of charge, and the discharging current will be highest when the capacitor is full of charge. This is shown in the graphs in Figure 2. 2.
