Most metals don't dissolve in solvents and have high melting and boiling points. To make sure that I get very accurate results, I will repeat all my measurements, and I will be aware of the risk assessment with this experiment. I will not touch the wire when the current is flowing so I do not receive an electrical shock; I will keep the current low so if I do touch the wire it will not be too dangerous...

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 I'll do six different readings, varying the length in each reading. ? Dependent variable ? what you'll measure. I'll measure the resistance in each reading...	3 / 755
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
