St James's C.E. School Centre No. 32153 John Foster GCSE Science Investigation Experiment to find out whether increasing or decreasing the length of nichrome wire affects its resistance. For this experiment, I will be finding out the resistance of a nickel-chromium wire of varying lengths. I will find out how much resistance occurs when I increase or decrease the size of the resistor (the wires length). Resistance is the property of an electrical conductor, to work against the flow of the current and change some of the electrical energy into heat. According to ohm's law, the quantity of resistance in an electrical circuit determines the amount of current flowing in the circuit for any given voltage applied to the circuit. The standard abbreviation for resistance is R - The symbol for ohms in an electrical circuit is the Greek letter ? (omega). Many of the electrical calculations use the letter G - conductance -...
