In the Geiger-Muller tube, particles ionize gas atoms. The tube contains a gas at low pressure. At one end of the tube is a very thin "window" through which charged particles or gamma rays pass. Inside the tube is a copper cylinder with a negative charge. A rigid wire with a positive charge runs down the center of this cylinder...

Resistance of a wire The points are very close to the line of best fit or even touching it. This showed that the results were directly proportional throughout the experiment, as the line does not curve suddenly or curve or bend at all in any way, as the gradient of the line stayed the same throughout...	2 / 316
resitence of wire So The theory behind these conclusions are: As the length doubles the resistance doubles. Resistance is caused by electrons bumping into ions. If the length of the wire doubles, the electrons bump into the ions twice as much so the resistance will double...	2 / 302
Resistance of a Wire Also i will turn off the power supply before changing the length of the wire Results 5 Volts wire nickel Chrome swg Length amps Volts Resistance? 50cm 0...	3 / 582
Investigating the resistance of wire This includes: · Not having the voltage too high, as the wire will get too hot. · Don't have the power on very long for each reading as this would make the wire hot and could easily cause a burn...	3 / 803
