The emitter-base junction of a transistor is forward biased whereas collector-base junction is reverse biased. If for a moment, we…
A transistor consists of two pn junctions formed by *sandwiching either p-type or n-type semicon-ductor between a pair of opposite…
While filters can reduce the ripple from power supplies to a low value, the most effective approach is a combination of…
Ripple Voltage As you have seen, the capacitor quickly charges at the beginning of a cycle and slowly discharges through RL…
A half-wave rectifier with a capacitor-input filter is shown in Below Figure. The filter is simply a capacitor connected from…
Peak Inverse Voltage Each diode in the full-wave rectifier is alternately forward-biased and then reverse-biased. The maximum reverse voltage that each…
A center-tapped rectifier is a type of full-wave rectifier that uses two diodes connected to the secondary of a center-tapped transformer,…
A full-wave rectifier allows unidirectional (one-way) current through the load during the entire 360° of the input cycle, whereas a half-wave…
All active electronic devices require a source of constant dc that can be supplied by a battery or a dc power…
As we know, forward bias produces current through a diode and reverse bias essentially prevents current, except for a negligible…
