Resistor is defined as an electrical component which is used for controlling temperature and voltage. There are two types of resistors: linear resistor and non-linear resistor. Resistors are identified with the help of color codes. Resistor finds application in demodulator.

There are various ways to prove that resistors obey Ohm's law (V=IR). Ohm's law says that voltage across a component is proportional to the current going through it, provided that the component's resistance is kept constant. To carry out an experiment to prove Ohm's law for a resistor, you need an ammeter to measure current and a voltmeter to ...
