Zener Diode as Voltage Regulator

1. VOLTAGE REGULATOR.=> it is any device that outputs a constant input voltage for any input voltage.voltage regulator is generally used to limit the voltage across any load that can be damaged ...

ZENER DIODE

1. WHAT IS ZENER DIODE?=> structurally Zener diode is just a heavily doped P-N junction diode. but is varies form a P-N junction by a lot in working and use. (stating that Zener diode is just he...

Biasing of P-N junction

=> P-n junction is a semiconductor that carries current in only one direction=> applying voltage across the terminals of the diode is called biasing=> based on the direction of the field a...

P-N junction diode

1.  WHAT IS P-N JUNCTION DIODE?=>  it is a semiconducor that carries current only in one direction.2. HOW IS A P-N JUNCTION FORMED?    => when you attach a p-type and an n-type semiconductor ...

Energy band theory of solids

1. WHAT IS A ENERGY BAND?=> like energy levels, energy bands are also permitted "region" where a electron can exist in a atom or a molecule.  as the name suggests, energy band are much broader p...
