Objectives:
1, Compare the resistance of different types of fit outs of change lengths.
2, Maintain a constant temperature and thickness of the wires.
Background information
Ohms justness states: that the current through a manager between twain points is directly relative to the potential difference crosswise the cardinal points, and inversely proportional to the resistance between them.
Ohms Law reflection: I=V/R basically, current= voltage/Resistance
conceive Ohms law doesnt apply when temperature changes
Resistance is measured in Ohms, and is related to the current in the circuit and voltage across the circuit. Basically, it is the ratio of the potential difference across a conductor to the current flowing through it. Arguably, resistance is inversely proportional to the current flowing through a conductor. This is illustrated in the law below.
Resistance= Potential difference (volt, v) / Current (ampere, A)
Many researchers pass over the years claimed that resistance is findd by a spacious range of factors. One of these factors is believed to be the length of wires. According to these researchers, the longitudinal the wire the greater the resistance. Conversely, the shorter the wire the slighter resistance.
This is depicted in the following diagrams.

Other factors highlighted in the literature that may influence resistance are the thickness and temperature of conductors. In relation to thickness, electrons collide with atoms more often in a thinner wire than they do in a thicker wire, as the former has less space than the latter. An electric current flows when electrons move through a conductor. A thin wire is believed to have fewer electrons to aim the current than a thick wire. This means that the thinner the wire the more resistance and the thicker the wire the less...If you want to get a full essay, order it on our website: Ordercustompaper.com
