Hey everyone,
For physics we need to carry out an expieriment where we hook a length of nicrome wire up to an ammeter and battery. The wire is on a ruler, and what we do is move the wires different distances from one another on the nicrome wire, and see what effect that has on the current. Obviously the voltage is kept the same throughout.
Also, what are some potential errors and variables for the experiments?
What I would like to know, is what effect this will likely have, what is the physics behind the phenomenon and what the relationship is. Relative formulas would also be helpful.
Just to put your minds at ease, this isn't cheating because we have been given this information to use, I have just never carried out the experiment out myself and therefore can't answer any of the questions.
Thanks in advance!
