Electrical resistance in a wire is a measure of the opposition to the flow of charge, electrons, or current 2 the resistance of a piece of wire does not depend on (b) wire mass 5. Factors affecting the resistance of a wire introduction: resistance is a force, which opposes the flow of an electric current around a circuit resistance is measured in ohms. Common wire gauges the common us wire gauges (called awg gauges) refer to sizes of copper wire the resistivity of copper at 20 c is about this table uses this value of resistivity, but it is known to vary by a few percent based on purity and process of manufacture.

Free and custom essays at essaypediacom take a look at written paper - resistance of a wire. A 12-gauge wire is wider than 14-gauge wire and thus has less resistance the lesser resistance of 12-gauge wire means that it can allow charge to flow through it at a greater rate - that is, allow a larger current.
The resistance in a piece of wire essay
A given piece of wire has an inherent resistance which is a combination of its composition to increase the resistance of a given wire you would need to change one of the items above either increase its length, decrease its cross section.
- The resistance of a wire essay - the resistance of a wire introduction in this investigation i will be trying to find out the resistance of a piece of constantan wire i know that according to ohms law, the pd.
- For good conductors and moderate currents, the resistance of a piece of wire r is directly proportional to its length l, provided its temperature remains constant this relationship can be written as.
- Free essay: the problem with using resistance as a measurement is that it depends not only on the material out of which the wire is made, but also the.
This student essay consists of approximately 5 pages of analysis of the effect the thickness of a wire has on resistance. Planning in this piece of coursework, i am going to investigate what affects the resistance of a piece of wire wire is made up of atoms electric current is a flow of electrons, and it is these electrons that collide with the nucleus of the atoms. Data analysis the investigation i did was to find the resistance of a piece if wire the piece of wire is my dependent variable throughout the investigation. In fact, it can be quite dangerous to build (directly connecting the poles of a voltage source together with a single piece of wire) resistance is the measure of opposition to electric current.
