Ohm's Law

Investigating Resistance
Electricity is the flow of electrons. Resistance is the slowing of this flow. Resistance will increase when there are more electrons for the current to collide with. It will also increase when the electrons are moving at a high speed. There are five main factors that affect resistance. These are
i.Length of wire
ii.Temperature of wire
iii.Voltage that is used to push current around circuit.
iv.Thickness of piece of wire.
v.Material.
i.If the length of the wire is increased, the resistance will increase. …
