Copyright © Phil Johnson and Shaun P. Roberts 2005. What are the 4 factors that affect resistance? What is an electrical current To find out how the length of a piece of wire effects the resistance Pages: 5 (1436 words) An Investigation into Factors Affecting Resistance of a Wire Pages: 5 (1467 words) Investigation to see if the length of any type of wire affects its resistance Pages: 7 (1962 words) The Length of a Wire Increases its Resistance Pages: 4 (1041 words) The objective for my coursework (as already stated above) is to investigate, starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long. Electricity. Factors affecting the resistance of a wire Therefore a temperature controlled room would improve the reliability of my results.

But this does not affect the speed. Premium This means that they need only a tiny amount of energy in order to allow the electron to move. For this we needed potential difference and current. 1692 Words | Background Information: Voltage(potential difference) And Current in a circuit The higher the potential difference and the lower the current means higher resistance. Beginning from 100cm and ending at 10cm. You must use thick wire to carry a large current, or the wire gets too hot and melts (like a fuse).. Electrical measurements, Alternating current, Ohm's law 552 Words | Premium The resistance of a wire decreases with increasing thickness. a continuous loop has been made connecting the negative end of an electrical source to the positive) it creates a path for electrons to pass through.

The resistance of a wire decreases with increasing thickness.

I have also added in range bars to show my highest and my lowest resistance. Premium How Does The Legnth Of A Wire Affect Resistance In A Circuit? Thickness The thickness of the resistor.

I will be using constantan wire starting of with 1m length and then decreasing it by 0.10m intervals down to 0.20m long.

The total length of the wires will affect the amount of resistance. Experiment on Wire and Resistance Correlation in a Circuit. R- Resistance Metallic bonding.

This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy.
