Factors affecting electrical resistance

I think that the range of my results was sufficient enough for me to draw a valid conclusion about how the length of the wire affected the resistance.

Thus, gauge wire is used in circuits which are protected by Amp fuses and circuit breakers. Due to which the electrical resistivity of the solid solution increases more rapidly with increase of alloy content. The cables are sized to the calculated load.

Resistance is similar to this. Electrons are lost due to conductive resistance over every part of the length of the wire. List two factors that affect the amount of electric current in a wire?

Otheraffecting factors include cross sectional area, temperature, andlength. Cold working is used to increase the mechanical strength of the metal. What two factors affect the amount of air resistance?

Electrical Resistance

Topic Menu Factors that affect the resistance of a wire The resistance of an object is a measure of the how reluctant current is to flow through that object. Examples of ohmic components are wires and resistors. The student asked "What would lower electrical resistance of a wire?

Some basic examples of these are: The variables I will control will be the type of wire resistivity and the cross-sectional area of the wire.

Four Factors Affecting Resistance

What if you have to transfer a certain power requirement over a certain distance? Type the name of the material and click the Submit button to find its resistivity. Now when you cool the conductor to extreme low temperates, it is very akin to adding oil to an engine.

A Amp circuit used for wall receptacles should be wired using gauge wire and a Amp circuit used for lighting and fan circuits should be wired using gauge wire. The equation below is used to work out the resistance of a component from measurements of the current flowing through it and the potential difference across its ends.Originally Answered: What factor does the resistance of a conductor depend on?

The resistance of a conductor (I assume you mean, electrical conductor), depend on the following main factors. The type of material employed.

The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Oct 03,  · A diode is an electrical one way street, which is useful sometimes in electronic circuits.

Current is allowed through a low resistance pathway in one direction, the resistance is very high in the reverse direction so no current flows. Apr 19,  · An Investigation Into the Resistance of a Wire - GCSE Physics Coursework. The free electrons keep bumping into atoms.

A wire's resistance depends on four main factors: Resistivity; Length of the wire areas of wires or even change the temperature of the wires deliberately and see how manipulating these variables affect the resistance Reviews: Variables Affecting Electrical Resistance.

The flow of charge through wires is often compared to the flow of water through pipes. The resistance to the flow of charge in an electric circuit is analogous to the frictional effects between water and the pipe surfaces as well as the resistance offered by obstacles that are present in its path.
