Length/resistance of a wire Brief How is resistance of a wire affected by the length of a wire. How will I do it? I will have to measure out lengths of bare wire, all of the same type of metal, thickness, and keep them at the same temperature (to keep the experiment reliable and precise) I will use constants of voltage and variables of lengths of wire. I will also measure the current and voltage by using a voltmeter and ammeter for extra reliability. I must take in to account that temperature is very important as it can lose energy in the particles and I will have to measure the resistance of the circuit without the bare wire. To measure the resistance of each length of wire by using the equation: R = V / I Where R = resistance V = Pd. Across the conductor I = current This formula will give me a result in Ohms (?) From the...
