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 mental retardation of this flow. Resistance allow ontogeny when in that location are to a greater extent electrons for the current to collide with. It go forth as well increase when the electrons are moving at a superior speed. There are five main factors that walk come out bulwark. These are i.Length of fit out ii.Temperature of electrify iii.Voltage that is used to adjure current around circuit. iv.Thickness of piece of electrify. v.Material. i.If the length of the wire is increased, the impedance 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 clog up faster. Due to this the electrons will collide with the wire particles more ofttimes than if the wire was cool. I.E ? Cool Wire Heated Wire iii.If the potential drop 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 amongst the electricity particles and the particles in the wire. I.E ? 2V 4V iv.The thicker the piece of wire, the less resistance thither will be.

This is because the electrons hold back more space to move in. Therefore, there will be fewer collisions between particles and this will subordinate the resistance. I.E ? 26 SWG 24 SWG v.As slightly materials are bett! er conductors than others, this will obviously affect the resistance. This is wherefore gold plugs are desirable in stereo systems. Aim To suss out what affects resistance. I provoke chosen to investigate length at 5cm intervals and thickness. I have chosen...
