for this essay I investigated Ohms Law. I investigated the effect that the length and the thickness of wire had on the resistance.

Investigating Resistance Electricity is the flow of electrons. Resistance is the slowness of this flow. Resistance allow ontogeny when in that location are to a greater extent electrons for the current to jolt with. It leave to a fault increase when the electrons are moving at a postgraduate speed. There are five main factors that walk out bulwark. These are i.Length of fit out ii.Temperature of fit iii.Voltage that is used to impel current around circuit. iv.Thickness of piece of fit out. v.Material. i.If the length of the wire is increased, the confrontation will increase. If the length of the wire is decreased, the resistance will decrease. This is because if the wire is increased from 10cm to 20cm the electrons will ready more wire particles to collide with. I.E ? 10 cm 20 cm ii.As with all solids, liquids and gases, if the wire is heated, the particles will gain more energy and will death faster. Due to this the electrons wi ll collide with the wire particles more oft than if the wire was cool. I.E ? Cool Wire Heated Wire iii.If the potentiality in the wire is increased, the heat of the wire will increase. As with ii. the particles will bear upon faster thus creating more collisions betwixt the electricity particles and the particles in the wire. I.E ? 2V 4V iv.The thicker the piece of wire, the less resistance on that point will be. This is because the electrons gather in more space to move in. Therefore, there will be fewer collisions between particles and this will chasten the resistance. I.E ? 26 SWG 24 SWG v.As slightly materials are better conductors than others, this will obviously affect the resistance. This is wherefore gold plugs are favorite(a) in stereo systems. Aim To suss out what affects resistance. I experience chosen to investigate length at 5cm intervals and thickness. I have chosen...
