What are the Factors that influence resistance?

Factors that effect resistance are: # Heat- At a higher temperature their will be more resistance as the atoms within the wire begin to swell and make it harder for the current to pass through the wire; this causes more resistance. # Length- As the length increases so does the resistance. This is because there is a larger space for the electrons to jump across and more atoms for them to get through to complete the circuit. # Cross-Sectional area- As the CS area increases the resistance decreases as there are more places for a greater current to travel through. # Material- Different materials have different densities. The denser a material the higher the resistance.
