What is the meaning resistance in electricity.

Measured in ohms electric resistance impedance ohmic resistance. When an electric current of one ampere passes through a component across which a potential difference voltage of one volt. Resistances are said to dissipate electrical energy as heat. Electrical resistance a material s opposition to the flow of electric current.

Resistance in electricity property of an electric circuit or part of a circuit that transforms electric energy into heat energy in opposing electric current. Resistance is the opposition that a substance offers to the flow of electric current it is represented by the uppercase letter r. Resistance is measured in ohms symbolized by the greek letter omega ω. The act of fighting against something that is attacking you or refusing to accept something.

Resistance converts electrical energy to thermal energy and in this regard is similar to mechanical friction. In electrical terms this is represented by two circuits with equal voltages and different resistances. Resistance involves collisions of the current carrying charged particles with fixed particles that make up the structure of the conductors. Ohms are named after georg simon ohm 1784 1854 a german physicist who studied the relationship between voltage current and resistance.

This brings us back to georg ohm.
