As a high school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta. Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current. This relationship is known as Ohm's law.

The charged electrons create charge, which are bind together to do work. The electric bulb, fan and other electronic equipment’s work by binding the electrons. Electricity is measured in units of power called as Watts and it is denoted by the letter W. Current can be defined as the rate at which the charge is flowing. An electric current can be measured using a device called as ammeter and the SI unit for measuring an electric current is the ampere. Voltage can be defined as the difference in charges between the two points. It can be measured by direct current (DC) and alternating current devices. Resistance is the tendency of a material to resist the flow of current. There are several factors that affect the resistance. These includes the material of a wire, thickness of wire, length of a wire and temperature of a wire. The resistance of an electricity is measured in Siemens, which is denoted by the letter S and the S.I unit of resistance is ohms which is denoted by the Greek alphabet symbol Omega - Ω. The resistance of any substance can be calculated by the Laws of Resistance. The main difference conductor and insulator is in conductor electric current flows freely whereas in insulator electric current cannot flows freely.
