Experiment -13: - To Identify Different Types of Resistors From physical Appearance.

 

Aim: - To Identify Different Types of Resistors From physical Appearance.

Materials Required: - Various types of resistors, Measuring instruments Voltmeter, Ammeter, Ohm meter etc.

Theory:-

Resistance is the property of a material which opposes the flow of electric charges through it. The unit for measuring resistance is Ohms. It is measured using the Ohmmeter.

Resistors are components used in electrical and electronic circuits for making different voltages required for different electronic components.

There are two types of Resistors:-

The Ohm value (resistance) of these resistors is constant and cannot be altered. The examples are carbon resistors, Ceramic resistors and Wire wound resistors.

Different types of Variable resistors

These resistors, the ohm value can be varying. The examples are potentiometer, Preset, Fan regulator etc.
