Resistance Of A Wire Coursework Diagram Mla For Movie Titles In An Essay

An electrical device having a resistance of 5 ohms would be represented as ), and represents the resistivity of the material (in ohm•meter).

Consistent with the discussion above, this equation shows that the resistance of a wire is directly proportional to the length of the wire and inversely proportional to the cross-sectional area of the wire.

First, the total length of the wires will affect the amount of resistance.A third variable that is known to affect the resistance to charge flow is the material that a wire is made of.Not all materials are created equal in terms of their conductive ability.In the same manner, the wider the wire, the less resistance that there will be to the flow of electric charge.When all other variables are the same, charge will flow at higher rates through wider wires with greater cross-sectional areas than through thinner wires.Those materials with lower resistivities offer less resistance to the flow of charge; they are better conductors.The materials shown in the last four rows of the above table have such high resistivity that they would not even be considered to be conductors.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.It is this resistance that hinders the water flow and reduces both its flow rate and its speed.Use the Resistivity of a Material widget to look up the resistivity of a given material.Type the name of the material and click the Submit button to find its resistivity.
