Diodes are electronic components that allow current to flow in one direction and block it in the opposite direction.

• Diodes are used in rectifiers to convert AC to DC

• They are also used in voltage regulators to maintain a constant voltage

• Zener diodes are used as voltage references

• Light-emitting diodes (LEDs) emit light when current flows through them

A diode is a semiconductor device that allows current to flow in only one direction.

• Diodes have two terminals: an anode and a cathode.

• When a voltage is applied to the anode, current flows through the diode.

• However, when a voltage is applied to the cathode, the diode blocks current flow.

• This is because the diode is designed to have a high resistance in the reverse direction.

• Diodes are commonly used in rectifiers, v...read more
