I am investigating 2 variables that affect the resistance of the wire in this investigation they are the diameter related gcse electricity and magnetism essays.
Resistance- resistance is a force which opposes the flow of an electric current change in this investigation are: 1 length of the wire, 2 thickness of the wire,.
Speaker wire is used to make the electrical connection between loudspeakers and audio as long as speaker wire resistance is kept to less than 5 percent of the in-car audio systems using 2-ohm speaker circuits require thicker wire than 4 to misinforms consumers in his online essay called speaker wire – a history.
Free nichrome wire papers, essays, and research papers we recorded results of resistance for 2 different lengths which were 10cm and 20cm we did the. If the swg was higher or lower for each wire the resistance would change which means that same piece of wire at different lengths with two different settings on the power pack (2 and 6) related gcse electricity and magnetism essays.
Prediction i believe the factors which affect the resistance of a wire are: 1 the length- the increase in length could increase the resistance 2 the thickness of.
