Electrical Resistance

Resistance is an electrical quantity that measures how the device or material reduces the electric current flow through it.

Electrical resistance. Electrical resistance synonyms electrical resistance pronunciation electrical resistance translation english dictionary definition of electrical resistance. Electrical resistance is the hindrance to the flow of charge through an electric circuit. Resistance also depends on the material of the conductor. It explains the relationship between voltage amount of electrical pressure and the current flow of electricity.

It is often utilized in probes used to monitor corrosion. When a voltage is applied across a substance there will be an. Electrical resistance a material s opposition to the flow of electric current. Electrical resistance shares some conceptual parallels with the notion of mechanical friction.

With more resistance in a circuit less electricity will flow through the circuit. The resistance of a wire is directly proportional to its length and inversely proportional to its cross sectional area. Every material has an electrical resistance and it is the reason that the conductor give out heat when the current passes through it. Definition of electrical resistance resistance also known as ohmic resistance or electrical resistance is a measure of the opposition to current flow in an electrical circuit.

Resistance is a measure of how much an object opposes the passage of electrons. The longer the conductor higher the resistance. Electric resistance welding erw is a welding process where metal parts in contact are permanently joined by heating them with an electric current melting the metal at the joint. The property of electrical resistance has important applications in electrical and electronic devices.

The smaller its area the higher its resistance. The si unit of electrical resistance is the ohm ω while electrical conductance is measured in siemens s formerly called mho s and then represented by. The resistance of an object depends in large part on the material it is made of. Electrical resistance explains the relationship between voltage and current.

Electric resistance welding is widely used for example in manufacture of steel pipe and in assembly of bodies for automobiles. The resistance is measured in units of ohms ω. Electrical resistance is the opposition to current within a circuit. The amount of resistance in a wire depends upon the material the wire is made of the length of the wire and the cross sectional area of the wire.

If we make an analogy to water flow in pipes the resistance is bigger when the pipe is thinner so the water flow is decreased. Resistance is measured in ohms symbolized by the greek letter omega ω.
