Semiconductors: p-n junction diodes

Diodes are semiconductor devices that are commonly used. In electrical engineering, a rectifier diode is a two-lead semiconductor that permits current to flow only in one direction. A P-N junction diode is often made by bringing together two different types of semiconductor materials, such as n-type and p-type semiconductor materials. The P-type side is referred […]

The components of semiconductor diodes are widely used in electrical appliances such as computers, laptops, phones, etc. These can also be referred to as a pn junction whose p region is connected to one diode and n is connected to another. These diodes made of silicon allow current to flow in them. Also, on the

To regulate the current flow in the circuit, we need specific resistance. Carbon composition resistors are ideal for fitting to resist the current to specified levels. Hence, they are also known as the fixed form of a resistor. However, metal wires like copper, aluminium and iron have resistances, but we can’t use them directly in

The potentiometer is a variable resistor which is used to control the resistance of electrical devices like motors. It consists of a dial or slider which has contacts on all its sides. When the slider is moved from one side to another, the intermediate contacts get closed and when it is released, all the contacts

“Resistor” refers to a basic component found in all electrical devices. A resistor seems to be a two-terminal passive electronic component. The resistor is being used to limit the passage of electric current in a circuit by its definition. A carbon resistor is a fixed type of resistor. And over a century has passed since

A closed path or loop made up of electrical components that allow electrons to flow through them is known as an electric circuit. The main components of an electric circuit are transistors, resistors, inductors, capacitors, and diodes. We can connect these components through an electric wire.
