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 retardent of this flow. Resistance allow ontogeny when in that location are to a greater extent electrons for the current to jar with. It willing in any case increase when the electrons are moving at a mellowed speed. There are five main factors that walk step forward bulwark. These are i.Length of fit out ii.Temperature of equip iii.Voltage that is used to concern current around circuit. iv.Thickness of piece of wire. v.Material. i.If the length of the wire is increased, the tube 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 dying 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 voltage 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 among 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 form more space to move in. Therefore, there will be fewer collisions between particles and this will smother the resistance. I.E ? 26 SWG 24 SWG v.As slightly materials are better conductors than others, this will ob! viously affect the resistance. This is wherefore gold plugs are pet in stereo systems. Aim To suss out what affects resistance. I acquit chosen to investigate length at 5cm intervals and thickness. I have chosen...
