Q3. What is the role of a diodein an electrical circuit
Ans. 
A diode is an electronic component that allows current to flow in one direction only.
• Diodes are commonly used to convert AC to DC in power supplies.

• They are also used to protect circuits from reverse polarity.

• Diodes have a forward voltage drop, typically around 0.7V.

• They can be used in rectifier circuits to convert AC to DC.

• Diodes are also used in signal processing circuits to separate AC and DC components.
