Cgse physics coursework resistance in wire essay

Step-up transformers are used to increase the potential difference from the power station to the transmission cables then step-down transformers are used to decrease, to a much lower value, the potential difference for domestic use. Move down the graph, from point to point, showing that the gradient decreases.

We can observe how the potential difference voltage is proportional to the current passing through it. Essay writing skills in ielts show me an outline for term papers thesis on spatial data mining medical literature review services creative writing tutor.

The examiners may put one in for a component for which you have never seen the graph, but you will be told what it is and be asked some simple questions about the information you can get from it. The material of wire used, copper, may not have been entirely a pure material. However, my reactions would have been similar on each of the parachutes.

Guaranteed to be delivered to your Email Address before your mentioned deadline! Lindenfeld Peter, Brahmia Suzanne White. This experiment was a fair test because other factors that could affect the resistance in a wire were kept constant; such as length, material of wire and temperature of wire.

Work done per coulomb of charge that passes between two points Kinetic energy per coulomb of charge that passes between two points Work done per coulomb of charge that passes between three points Work done per ampere of current that passes between two points Strictly speaking, it should really be called electrical potential difference but at GCSE, potential difference is acceptable, when used in the correct context 2.

Resistance of wire with cross sectional area Resistance of wire with cross sectional area 0. Knowing the current and potential diffence, you can calculate resistance using the above equation. They're often used in thermostats. The length of the wire increases. The resistance of an LDR decreases as light intensity increases.

Institute of Physics, 2 Stof its greater andard International 3 Also called a conductive elements Physics Investigation: Material Quantity Function Battery Eliminator 1 Provides circuit with charge, eliminating higher current.

Also displays average resistance of each circuit. Diagram 1 illustrates that there was less air resistance because the surface area of the parachute is smaller than that the parachute in diagram 2 i.

The thickness of the wire decreases. Looking at the graph, it is apparent that the the votlage values of W2 are greater than that of W1, indicating that the resistance in W2 is lesser than that of W1.

The energy is supplied by the power source for the electrical circuit. Table 1 Fair Test To ensure the investigation is fair I will keep all the variables the same apart from the one I am changing.

None of the lines are in constant suddesting that the resistance in neither wires is constant, this may be a rsult of errors in the experiment.

Lab Report Explained: Length and Electrical Resistance of a Wire

This is called Ohm's Law. Another way I could have timed would be if I used some sort of machine that could have timed the fall of the parachute, but as afore mentioned it would have cost money and would not be readily available.GCSE Physics Year 10 coursework- Resistance of a wire Aim: In my experiment I am aiming to discover what happens to the resistance of a wire as the length is changed.

Independent variables - Length of wire - Diameter of wire - Material of wire The factor I will be investigating is length.
