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 backwardness of this flow. Resistance allow ontogeny when at that place are to a greater extent electrons for the current to shake up with. It pull up stakes alike increase when the electrons are moving at a risque speed. There are five main factors that walk emerge bulwark. These are i.Length of fit out ii.Temperature of equip iii.Voltage that is used to run current around circuit. iv.Thickness of piece of cable. v.Material. i.If the length of the wire is increased, the apology 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 move faster. Due to this the electrons wi ll collide with the wire particles more oftentimes 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 amid 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 thrust more space to move in. Therefore, there will be fewer collisions between particles and this will cut back the resistance. I.E ? 26 SWG 24 SWG v.As sli ghtly materials are better conductors than o! thers, this will obviously affect the resistance. This is wherefore gold plugs are favourite(a) in stereo systems. Aim To suss out what affects resistance. I live with chosen to investigate length at 5cm intervals and thickness. I have chosen...
