Investigating The Resistance Of a Wire

Planning

The experiment is safe because the voltage from the multimeter will do no harm to you and you should not use it near water.

Method

I am investigating the resistance of a wire and testing what happens to the current

Middle

Diagram

I will make the experiment accurate by doing all of the below and do the same test three times to work out an average

  • 1.Using the same equipment
  • 2.Measure the wire.
  • 3.Connecting everything together properly
  • 4.Once set up do not disturb the experiment
  • 5.Make sure the multimeter is set to Ohms
  • 6.Using the setting on the multimeter

Conclusion

lass="c10 c14">The wire the same width.The same material.The same temperature.

Prediction

I predict the longer the wire the more power will be resisted. That is because in a longer piece of wire the electrons collide with the atoms.
