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 deceleration of this flow. Resistance allow ontogeny when at that place are to a greater extent electrons for the current to clash with. It will likewise increase when the electrons are moving at a luxuriously speed. There are five main factors that walk turn out bulwark. These are i.Length of fit out ii.Temperature of conducting cable iii.Voltage that is used to fight down current around circuit. iv.Thickness of piece of wire. v.Material. i.If the length of the wire is increased, the underground 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 break down faster. Due to this the electrons will collide with the wire particles more a great deal than if the wire was cool. I.E ? Cool Wire Heated Wire iii.If the electric potential 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 surrounded by the electricity particles and the particles in the wire. I.E ? 2V 4V iv.The thicker the piece of wire, the less resistance in that location will be.

This is because the electrons perplex more space to move in. Therefore, there will be fewer collisions between particles and this will hack the resistance. I.E ? 26 SWG 24 SWG v.As slightly mate! rials 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 render chosen to investigate length at 5cm intervals and thickness. I have chosen...
