4. What is
diode?
A diode is an
electrical component
designed to conduct
electric current in only
one direction.
It has two ends (or
terminals), each with an
electrode of a different
charge.
6. A diode is
formed by
joining two
equivalently
doped P-Type
and N-Type
semiconductor.

7. Biasing
Biasing in electronics means establishing
predetermined voltages or currents at
various points of an electronic circuit for
the purpose of establishing proper
operating conditions in electronic
components.
1.Forward Biasing
2.Reverse Biasing
9. FORWARD AND REVERSE
BIAS
Forward biasing means
putting a voltage across a
diode that allows current to
flow easily,while reverse
biasing means putting
a voltage across a diode in the
opposite direction.
