Capacitor Discharging

The transient behavior of a circuit with a battery, a resistor and a capacitor is governed by Ohm''s law, the voltage law and the definition of capacitance. Development of the capacitor charging relationship requires calculus methods and involves a differential equation.

Capacitor Discharging

To discharge a capacitor, the power source, which was charging the capacitor, is removed from the circuit, so that only a capacitor and resistor can connected together in series. The capacitor drains its voltage and current through the resistor.

Charging and Discharging a Capacitor

When the capacitor voltage equals the applied voltage, there is no more charging. The charge remains in the capacitor, with or without the applied voltage connected. The capacitor discharges when a conducting path is provided across the plates, without any applied voltage.

Charging and Discharging a Capacitor

Capacitor can be temporary batteries. Capacitors in parallel can continue to supply current to the circuit if the battery runs out. This is interesting because the capacitor gets its charge from being connected to a chemical battery, but the capacitor itself supplies voltage without chemicals.

Charging and Discharging a Capacitor

The capacitor charges to the applied voltage because it takes on more charge when the capacitor voltage is less. As soon as the capacitor voltage equals the applied voltage, no more charging current can flow. Note that any charge or discharge current flows through the conducting wires to the plates but not through the dielectric.

CHARGE AND DISCHARGE OF A CAPACITOR

An electrical example of exponential decay is that of the discharge of a capacitor through a resistor. A capacitor stores charge, and the voltage V across the capacitor is proportional to the charge q stored, given by the relationship. V = q/C, where C is called the capacitance.

Capacitor in Electronics

A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
