A diode is an electronic component that allows current to flow in only one direction. There are two types of transformers: step-up and step-down.

• Diode is a semiconductor device that has two terminals and allows current to flow in only one direction

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

• Transformers are devices that transfer electrical energy from one circuit to another through electro...read more

Transformers are electrical devices that transfer energy from one circuit to another through electromagnetic induction.

• Transformers work on the principle of electromagnetic induction

• They consist of two coils, primary and secondary, wound around a magnetic core

• When an alternating current flows through the primary coil, it creates a magnetic field which induces a voltage in the secondary coil

• The voltage in the secondary ...read more

Induction motor works on the principle of electromagnetic induction.

• It has a stator and a rotor.

• The stator has a set of windings that are connected to an AC power source.

• The AC current in the stator windings creates a magnetic field that rotates around the stator.

• This rotating magnetic field induces a current in the rotor windings, which in turn creates a magnetic field in the rotor.

• The interaction between the stator a...read more

A rectifier is an electronic device that converts AC to DC voltage.

• Rectifiers are used in power supplies to convert AC voltage to DC voltage.

• They are commonly used in electronic devices such as radios, televisions, and computers.

• There are two types of rectifiers: half-wave and full-wave.

• The diagram of a rectifier typically shows a transformer, diodes, and a load resistor.

• Rectifiers are important in ensuring that electr...read more

The function of the inverter is to convert DC power to AC power.

• Inverters are commonly used in solar power systems to convert DC power from solar panels to AC power for use in homes and businesses.

• Inverters can also be used in cars to convert DC power from the battery to AC power for charging devices.

• There are two types of inverters: pure sine wave and modified sine wave, with pure sine wave being the more expensive an...read more
