Physics coursework theory - resistance of a wire thickness (cross sectional area of the wire), length, and temperature all have some effect on the amount of resistance created in a wire. What factors affect the resistance of a material a) length - the further electrons have to travel through material, the more collisions they will have so the higher the value of resistance b) area - a bigger area means that in any 1 second more electrons will be able to travel through a piece of wire. The wire shunt has almost no resistance and it is in parallel with a bulb having resistance therefore all the current follows the zero (or extremely low) resistance path phy2049: chapter 27 25 circuits. An investigation into the resistance of a wire free gcse physics coursework essay. The resistance of a wire increases as its temperature increases electricity the resistance of wires-temperature does the resistance of a wire depend on its temperature as the temperature of the material increases, the ions of the material vibrate more and this increases the number of collisions as electrons move through the wire. A battery is connected to a resistor as charge flows, the chemical energy of the battery is dissipated as slide 22-10 b c d current voltage the resistance of a wire depends on its dimensions and the resistivityof its material: resistance of a wire in terms. Exam 2 solutions 1 two cylindrical resistors are made of the same material and have the same resistance the resistors, r1 and r2, have different radii when the wire is heated to 145° c the current drops to 194 a.

Class practical investigating the changing resistance of a wire as it heats up apparatus and materials power supply, low voltage, dc eg 12 v, 4 a at least rheostat (10 - 20 ohms) rated at 5 a at least aluminium container (eg. Where to buy resistance wire the current details we have are v b rewinds: they are selling resistance and copper wire at very competitive prices, are pleasant to deal with, and can turn orders round very quicklypostage and packing are also very reasonable - their details are as follows.

As wire resistance increases so does cable heating awg wire gauge for current capacities of course any of those wire gauges will work for a speaker system, but as the cable run increases the gauge or wire diameter should also increase. An investigation into the resistance of a wire - hubpages free gcse physics coursework essays an investigation into the resistance of a wire noticed that if you double the length of the wire, the resistance is roughly physics coursework investigating resistance of wires and its physics coursework investigating resistance of wires.

Resistivity and resistance physics lab vii objective in this set of experiments, the diﬁerences between resistance and resistivity will be ex- resistance of the wire, the voltage drop across the wire, and the current passing through the wire. Resistance decreases if the cross-sectional area is increased this sometimes confuses people, as it's not obvious look at these two pieces of metal: the narrow wire has fewer paths available for the electrons to move through whilst the larger wire has many more routes they could take this makes conduction easier.
