Capacitors and their Function in Electronic Devices

Capacitor Function in Alternating Current (AC) Circuits In AC circuits, capacitors exhibit a continuous cycle of charging and discharging due to the alternating nature of the current. The current leads the voltage by 90 degrees in phase, which means that the current reaches its peak one-quarter cycle before the voltage does.

The expression in Equation ref{8.10} for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference (V = q/C) between its plates.

Parallel Plate Capacitors: Components and Applications

Capacitance and Its Determinants The capacitance of a parallel plate capacitor, denoted by C, is the measure of its charge storage capability. It is directly proportional to the electrodes'' surface area (A) and the dielectric''s permittivity (ε), and inversely proportional to the separation distance (d) between the plates.

Fundamental Capacitor Functions in the World of Electronics

When placed in parallel with a signal path, capacitors take on a bypassing function. They allow DC to continue along the wire, but they divert high-frequency signal components to ground. In other words, capacitors play a role in low-pass filters, offering a low-impedance path for high-frequency signals to ground.

A large capacitor like the 2200 uF act as a "reservoir" to store energy from the rough DC out of the bridge rectifier. The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output.
