A diode is an electronic component that allows current to flow in only one direction.

• It has two terminals, an anode and a cathode.

• It is commonly used in rectifiers, voltage regulators, and signal limiters.

• It can be made of various materials such as silicon, germanium, or selenium.

• It has a forward voltage drop that varies depending on the material and current flow.

• It can be used to convert AC to DC in power supplies.

• Exa

Voltmeter measures potential difference in parallel and ammeter measures current in series due to their internal resistance.

• Voltmeter has high internal resistance and measures potential difference across two points in parallel

• Ammeter has low internal resistance and measures current flowing through a circuit in series

• Connecting voltmeter in series would cause a voltage drop and affect the accuracy of measurement

• Connecti...read more

Photodiode is a semiconductor device that converts light into electrical current.

• Photodiode operates in reverse bias mode

• It is used in light detection and optical communication systems

• It has high sensitivity and fast response time

• Examples include PIN photodiode and avalanche photodiode
