Resistance of a wire free gcse physics coursework essay when these electrons move, they create an electric current conductors have. Physics gcse coursework:factors affecting the resistance of a wire and a high volume of electricity, so we wore eye protection and lab coats all of the time.
Factors affecting resistance of a wire introduction the objective of this investigation is to find out the factors affecting the resistance of a wire in an electrical. The resistance to the flow of charge in an electric circuit is analogous to the frictional effects between water and the pipe surfaces as well as the resistance.
The electrical resistance (r) of a circuit component as given by ohm's law is the ratio of voltage (v) to current (i), usually expressed as v = ir it should not be. Electrical resistance can be considered rather dryly as the r in v = ir however, we can show its effects more spectacularly as a shower of sparks when wire.
