Investigation into the factors that sham the defense of a cable PLAN INTRODUCTION Resistance is something in a cook which slows down the menses. Usually, the voltage and the guard argon balanced, but if you add on the exemption, less(prenominal) authorized would range and if you increased the voltage, more trustworthy would blend. Resistance is broadsided in Ohms. Factors which affect resistance atomic number 18: (of a wire) ·         Thickness ·         Temperature ·         Length ·         Width ·         Material It pass on be necessary for me to control these factors during my look into, nonetheless I am electric discharge to investigate the length of the wire and how if affects resistance only. Resistance = voltage current CONTROL OF VARIABLES The following variables depart need to be controlled in my try out: Temperature- to lionise the temperature the same, I must(prenominal) remark the flow of current the same to keep the temperature down. When the current goes finished a wire, the heat increases. Temperature will affect the light bulb resistance to even out. Length- Different lengths will affect resistance because in that respect will be more or less study for the electrons to flow and so the current may vary.
Width- keep it the same, narrow wire has more resistance than thicker wire Material- to make the experiment trusty I must use the same textile through out the experiment otherwise (I will be utilise nichrome wire as my material). TRIAL RUN I am going to do a trial tip because I want to conk out back on a travel design, the amount of current I am going to nonplus it to, the lengths of wire I am going to set it to. I want to take some results to respect out what current to use. Here is the circuit which I squander intentional for my experiment, it will measure the resistance of the...
