Q1. What id diode ?
Ans. 
A diode is an electronic component that allows current to flow in one direction and blocks it in the opposite direction.
• Diodes are made of semiconductor materials, such as silicon or germanium.

• They have two terminals: an anode (positive terminal) and a cathode (negative terminal).

• When a diode is forward-biased, it allows current to flow through it.

• When a diode is reverse-biased, it blocks the current.

• Diodes are commonl...read more

Q2. Draw the diagram of diode
Ans. 
A diode is a two-terminal electronic component that allows current to flow in one direction and blocks it in the opposite direction.
• A diode has an anode and a cathode terminal.

• It is represented by a triangle with a line at the base.

• The arrowhead of the triangle points towards the cathode terminal.

• The line at the base represents the anode terminal.

• The symbol of a diode is often accompanied by its part number or label.
