Difference Between Ohms And Watts

Debraj Paul

Ohm means Resistance

Resistance is the property of a material to resist an electrical current flowing through it.

The measuring unit of this resistance is called the ohm which is represented as the omega sign, Ω. It is named after the German physicist Georg Simon Ohm. The Ohm’s Law is expressed as I = V / R, where I is electrical current (Amperes), V is the Voltage and R is Resistance (Ohms). That means a current is equal to the voltage divided by the resistance. Ohm is the standard unit of electrical resistance as per the International System of Units, and it also stands for the reactance in Alternating Current and Radio frequency applications. An ohm is equivalent to a volt per ampere. The unit of conductance is called “mho” which is a reverse spelling of the word “ohm”. The ohm is defined as the resistance between two terminals of a conducting material when a constant potential difference of 1.0 volts is applied to produce 1.0 ampere current in the conducting material, provided there is no electromotive force. The flow of electrons through a material is directly proportional to its pressure on the electrons and its cross sectional area.

All electrical circuits will have a voltage source, either as Direct current (DC) like a battery or an Alternating Current (AC), such as load. When connected, the current (A) flows from the negative terminal to the positive terminal along the wire. During this process, a resistance against the flow of the current is generated in the wire, which is measured as ohm. And the quantity of power developed subsequent to the resistance, either in the form of light or in the form of heat, is measured as Watt (W). An ampere (amp) is the amount of current in a circuit, whereas, watt is the quantity of electrical power generated by the circuit per second.
