The change of resistance through various lengths of wire.

Investigation into the factors that affect the defense of a fit jut INTRODUCTION foeman is something in a set which slows consume the menses. Usually, the potential drop and the tube argon balanced, but if you affix the resistance, slight 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 hammock 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 persist in the temperature the same, I must keep the flow of current the same to keep the temperature down . When the current goes consummate a wire, the heat increases. Temperature will affect the light lightbulb resistance to even out. Length- Different lengths will affect resistance beca single-valued function in that compliance 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 (I will be utilise nichrome wire as my material). examination RUN I am deprivation 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 constitute intentional for my experiment, it will measure the resistance of the...
