3. Whatis
diode?
A diode is an
electrical component desi
gned to conduct electric
current in only one
direction.
Ithas two ends (or
terminals), each with an
electrode of a different
charge.

4. Symbol
DIODE

5. A diode is
formed by
joining two
equivalently
doped P-Type
and N-Type
semiconductor.

1. Forward Biasing
2. Reverse Biasing

7. Forward and
Reverse Bias

8. FORWARDBIAS

9. REVERSEBIAS

10. 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.

11. V-I Charecteristics
Using V-I
characteristics
of the diode, it
is easy to find
the voltage
and current in
the circuit
which
contains
the diode.
