Ripple (specifically ripple voltage) in electronics is the residual periodic variation of the DC voltage within a power supply which has been derived from an alternating current (AC) source. ... Ripple voltage originates as the output of a rectifier or from generation and commutation of DC power.

Residual current circuit breaker (full form of the RCCB) or residual current device (RCD) is a current sensing electro-mechanical device that breaks an electric circuit in case of a fault. It operated, whenever the difference between line and neutral current (called residual current) becomes more than the set value.

PCB is an acronym for printed circuit board. It is a board that has lines and pads that connect various points together. In the picture above, there are traces that electrically connect the various connectors and components to each other. A PCB allows signals and power to be routed between physical devices.

PWM and PPM Introduction PWM stands for Pulse Width Modulation and PPM stands for Pulse Position Modulation. PWM is a technique used to relay data in the form of a varying pulse width. In PPM (Pulse Position Modulation) the analogue sample values determine the position of a narrow pulse relative to the clocking time.
