A diode is a two-terminal electronic component that allows current to flow primarily in one direction, functioning as a one-way valve. It plays a vital role in protecting circuits from power surges and converting AC to DC for improved power supply. Diodes are widely used in applications such as rectification, voltage multiplication, and reverse polarity protection.

4. FUNCTIONS OF A DIODE
• Diodes acts like a one-way valve,
permitting current to flow in one
direction called forward bias but also
blocking it in the opposite direction
referred as reverse bias.
• This process of controlling current flow
is crucial as it protects the circuit from
sudden power connection.
• Other than that, diodes can also
function in a way that it turns AC into
DC improving the power supplies for
electronic devises.
