A current of electricity is the flow of negatively charged electrons around a circuit. When the valence electron in any atom gains sufficient energy from some outside force, it can break away from the parent atom and become what is called a free electron. For example, if the length of the wire is doubled, then the amount of atoms will also double, resulting in double the amount of collisions it had before.

Introduction resistance is measured in ohms (â). Some materials have virtually no resistance when they are cooled down to absolute zero, they are called super conductors. This is because as they were bent, they may have been longer or shorter than they were meant to be.

The circuit will involve an ammeter, voltmeter, variable resistor, wire, battery and crocodile clips. These are temperature, the material of the wire and the thickness of the wire. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. The points follow a straight line, and importantly the line goes through (0,0).

    Papers - investigating the resistance of a wire the aim of this investigation is to see how the length of a wire affects its resistance. The voltmeter and ammeter were quite accurate, showing results to 2 decimal places. The type of material will affect the amount of free electrons, which are able to flow through the wire.

    This will result in a greater amount of heat loss, which indicates an increase in resistance. The following picture shows a complete circuit that the electrons can follow to produce current. The si unit for electrical resistivity is the ohm meter.

    In my results, as the length of the wire increased, so did the resistance. Papers - investigating the resistance of a wire aim i am going to investigate what factors affect the resistance of a wire. This is the cause of resistance and where electrical energy is turned into heat energy. Resistance resistance occurs when the electrons travelling along the wire collide with the atoms of the wire.

    MLA Citation: "Lab Report: Testing How the Length of a Wire Determines its Resistance." 123HelpMe.com. 16 Feb 2017 Thevenin’s, Norton’s, and Maximum Power Transfer TheoremsOhm’s Law would suggest an infinite current (current = voltage divided by zero resistance). Yet, the experiment described yields only a modest amount of current.
