How does Length affect resistance?
Coursework

Aim
To find out how the length of a wire can affect resistance.

Factors affecting resistance

 Temperature
 Length of wire
 Thickness
 Type

Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit.
Resistance is measured in ohms. The symbol for an ohm is Ω
Here is the rule for working out the resistance of a circuit: V/I = R or
V - Volts
I - current
R - resistance

Variables

• length of wire
• thickness
• type of wire
• current
• voltmeter
• temperature

Dependant variables

• length

Prediction

As we are looking at length this is my prediction:
I predict that the longer the wire the higher the resistance. This is because electrons have to travel pass more atoms and collisions between the electrons and atoms are made likely rather than in a......
