An Investigation Into Electrical Resistance
Part 1 of Paper
....rical current. The quantity of resistance in an electric circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. The resistance of an object is determined by the nature of the substance of which it is composed, its resistivity, accounting for its dimensions and it.... Part 2 of Paper
.... piece of wire being investigated, and a voltmeter connected in parallel with the wire. The ammeter is placed in series with the wire. An ammeter has a low resistance, so that it introduces as little extra resistance as possible into the circuit. The voltmeter is connected in parallel with the wire. Voltmeters have a high resistance, so the current they take is usually negligible.
We decided on the variables that could affect the resistance of a wire:
