Question

what is meant by resistance of wire​

Answer 1

Answer:

Resistance wire is wire intended for making electrical resistors. It is better if the alloy used has a high resistivity, since a shorter wire can then be used.

To calculate the resistance R of a wire, we need to know three things: its length – the longer the wire, the greater its resistance. its cross-sectional area A – the greater the area, the less its resistance. the resistivity of the material r – the greater the resistivity, the greater its resistance.

Answer 2

Answer:

Resistance is defined as the opposition to the flow of electrical current through a conductor. It's important to point out that conductivity and resistivity (the property that determines final resistance) are inversely proportional.
