# Resistance of Wire

Extracts from this document...

Introduction

## Aim

The aim of this investigation is to investigate the resistance of a wire by using one of the factors, which will have an affect on the resistance.

## Variables

Resistance of wire can be affected by the following factors:

• Length of wire
• Make of wire
• Diameter of wire
• Temperature of wire

The variable in which I will change for my investigation will be the LENGTH of the wire.  I have chosen this variable to change, as it will be easy to measure and to do.

Background

Resistance is calculated with the following equation:

Resistance (in ohms) = Voltage (in volts) / Current (in amps)

Middle

If I plot a graph of length on the x-axis against resistance on the y-axis. From the relation R = ? L /A which corresponds to the st. line equation ? Y=max the graph should be a st. line passing through the origin where "m" is the gradient of the st.

I would also investigate other factors, such as temperature, voltage and current, and see how these effect the resistance. I would also do the experiments under different conditions such as temperature and pressure to see if it makes any difference to resistance.

They are a different type of metal from the Nichrome wire and may have different properties and therefore different resistance. Therefore the resistance of the Nichrome wire showed up on the multimeter was slightly more than it actually was. To solve this problem, I would have finded out the resistance

1. ## Resistance of a Wire

Temperature The atoms in wire vibrate. This is a slight movement but can still create an impact on how much space the electrons have around them. This movement means that the atoms are likelier to hit the electrons when vibrating.

2. ## The resistance of a wire.

I predict that the longer the wire, the higher the resistance. This is because in a longer wire, there are more wire particles that electrons can bump into. Resistance is caused by electrons colliding with wire particles. If there are more wire particles, the chance of an electron colliding with a wire particle will be higher.
