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