A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)

A Complete Guide to Capacitors

Filter AC noise from DC circuits – any AC signals that may be on a DC bias point, power rail, or other nodes that need to be free of a particular varying signal should be removed by the capacitor. It must also be able to withstand the supply voltage while supplying and absorbing the levels of current arising from the noise on the rail.

RC Integrator Theory of a Series RC Circuit

For an RC integrator circuit, the input signal is applied to the resistance with the output taken across the capacitor, then V OUT equals V C.As the capacitor is a frequency dependant element, the …

Capacitive Pressure Sensor Working Principle

The capacitance pressure sensor is a pressure measurement device, which converts an applied pressure into a current signal, Like 4-20mA. Capacitive pressure transducers are used in many control and monitoring applications, such as flow, airspeed, level, pump systems, or altitude.
