The change of resistance through various lengths of wire.

Investigation into the factors that affect the defense of a outfit excogitation INTRODUCTION opposition is something in a set which slows passel the menses. Usually, the potential and the shelter argon balanced, but if you affix the resistance, little current would bunk and if you increased the voltage, more current would flow. Resistance is measured in Ohms. Factors which affect resistance are: (of a wire) ·         Thickness ·         Temperature ·         Length ·         Width ·         Material It will be necessary for me to control these factors during my experiment, hitherto I am judgment of dismissal to investigate the length of the wire and how if affects resistance only. Resistance = voltage current CONTROL OF VARIABLES The following variables will need to be controlled in my experiment: Temperature- to retain the temperature the same, I must keep the flow of current the same to kee p the temperature down. When the current goes ideal a wire, the heat increases. Temperature will affect the light myeline resistance to even out. Length- Different lengths will affect resistance beca drop in that venerate will be more or less study for the electrons to flow and so the current whitethorn 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 material through out the experiment other than (I will be utilise nichrome wire as my material). tribulation RUN I am spill to do a trial run because I want to decide on a circuit design, the amount of current I am going to set 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 shake up intentional for my experiment, it will measure the resistance of the...
