Risk Assessment To keep the experiment safe I shall keep electrical conductors away from the plug sockets. I will take care not to hurt myself or anybody else with the crocodile clips. I will also not turn the power socket on full so as that the wire does not burn or set fire to any surrounding objects or burn anybody. Preliminary work Firstly I assembled the apparatus as shown in the diagram below. For the wire I used 34 standard wire gauge wire. I then took measurements placed the two wire ends marked with an X...
Voltmeter reading by the Ammeter reading, giving me the resistance. This experiment would then be repeated three times so as to determine any anomalous results.

Diagram of apparatus for alternative experiment
I predict that the readings on the Voltmeter and Ammeter would be higher but when divided and the resistance worked out that the resistance would be very similar to that of the results worked out in my main experiment. This would be a useful experiment to carry out alongside my other to support my theory and satisfy my aim.
Electromagnetism experiment: Introduction: I start the introduction with a question: Will increasing current in an electromagnet increase the power of the electromagnet? The electromagnet we will be making is a very primitive one compared to that of the complexity of modern electromagnets found in machinery, but the...

Aim: To establish whether a variation in the voltage will affect an electromagnet"s strength Plan: I plan to try and make the strongest possible electromagnet using insulated copper wired coiled around an iron core Copper is used because it has a low electrical resistance, this means that it is easy...

For this project I want to investigate the factors affecting the resistance of a metal wire. Factors that effect the resistance of a wire are: Length Diameter Cross-sectional area worked out from this. Material used Temperature Of the above variables, I will be varying...

The Problem In this experiment I will be trying to uncover the relationship between springs, which are placed in parallel, and series in relation to Hooke's law. Prediction I predict that the springs in parallel will be approximately half the length of the spring that is by...
