Opto coupler are designed to provide complete electrical isolation between an input and output circuits. The useful purpose of isolation is to provide protection from high voltage Read more about Opto Coupler
There is grater concentration of holes in P-region and electrons in N-region. This deference in concentration establishes a density mismatch across the junction resulting in majority carrier Read more about FORMATION OF DEPLETION LAYER IN DIODE
full wave bridge rectifier consists of four diodes under the condition in which four diodes are connected the called bridge circuit. So due to this type of circuit is named bridge rectifier.
If we provide energy to an electrode then the electrons in the outer most shell of the atom of that metal gain enough energy to erect form the surface of that metal or electrode.
A CRT is an electronic tube designed to desplay electrical data. It consists of following main four parts. Focusing anode deflection coils, cathode and vacuum tube.
Diode has a property that is ability to conduct current in only one direction. Due to this property diodes are used in rectifier circuits. As rectification is the process to convert AC signal to Pulsating DC.
To remove the AC components from a rectifier circuit a filter is used. A filter circuit is a device to remove the AC components of rectified output. A filter circuit is a combination of inductor and capacitor and is called LC filter.
The figure shows the transistor connected in common emitter configuration and the figure also shows the hybrid equivalent circuit of such a transistor.
