Resistance Of a Wire

Investigating the effect aloofness has on the underground of a wire Aim The aim of this test is to find protrude what effect distance has on the resistance of a wire. The live, potency and resistance of a conductor are related by the by-line equation: V = I x R (Voltage = Current x Resistance) Ohms legality states that the current by dint of a wire is relative to the PD a frustrate it, provided that the temperature of the wire remains constant. I give exercising Ohms law in my experiment to think the effect distance has on the resistance of a wire. Variables Controlled: Temperature, cross sectional area, and strong of the wire. Independent: Length of the Wire Dependent: Resistance, victimization the emf and current results I depart collect Description of a fair test I will repeat the experiment 10 times at each length using a rheostat for average results. These average results will contain that, should whatever experimental error take place, it wont be very significant as the nine former(a) goodish results should cancel it out. I will use a discombobulate in my circuit to control the temperature of the wire, as Ohms integrity states that the temperature must remain constant. I will likewise use two 1V batteries, and will not change those batteries at all time during the experiment.

Prediction I predict that the resistance of the wire will increase as the wire length also increases. scientific theories that explain my prescience The first surmise Im basing my prediction on is Collision Theory, where vacate electrons collide with oppositely supercharged atoms. Therefore, the longer ! the wire, more collisions should occur, nub resistance will increase; because more collisions mean the lazy they will move. Ohms Law is the second theory Im basing my prediction on. Ohms law is used to prefigure resistance in the following equation. R = V/I (Resistance = Voltage / Current) Ohms Law states that the current through a wire is proportional to the PD crosswise it, provided that the...If you want to stomach a full essay, order it on our website: BestEssayCheap.com
