Nisha Patel 11E Mr. Treacher My aim in this investigation is to find out how the length affects the resistance of a wire. Before I start doing experiments and testing thing I need to predict what I think will happen. My theory is that as the length of the wire increase, the resistance will increase proportionally. To support my theory I have below written reasons for it, supported by scientific knowledge. What is resistance? Resistance, in electricity, property of any object or substance to resist or oppose the flow of an electrical 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, according to Ohm's law. The unit of resistance is the ohm, the amount of resistance that limits the passage of current to one ampere when a voltage of one volt is applied to it. The standard abbreviation for electric...
