for this essay I investigated Ohms Law. I investigated the
effect that the length and the thickness of wire had on the
resistance. Electricity is the flow of electrons. Resistance is
the slowing of this flow. Resistance will increase when there
are more electrons for the current to collide with. It will also
increase when the electrons are moving at a high speed. There
are five main factors that affect resistance. These are i.Length
of wire ii.Temperature of wire iii.Voltage that is used to push
current around circuit. iv.Thickness of piece of wire. i.If the
length of the wire is increased, the resistance 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 have more wire particles to collide
with. 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 will collide with the
wire particles more fre
