The longer the wire, the more resistance that there will be.There is a direct relationship between the amount of resistance encountered by charge and the length of wire it must traverse.As shown by the equation, knowing the length, cross-sectional area and the material that a wire is made of (and thus, its resistivity) allows one to determine the resistance of the wire.

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.
The resistivity of a material is dependent upon the material's electronic structure and its temperature.
For most (but not all) materials, resistivity increases with increasing temperature.
Resistance is a numerical quantity that can be measured and expressed mathematically.
The standard metric unit for resistance is the ohm, represented by the Greek letter omega - .The electrons encounter resistance - a hindrance to their movement.While the electric potential difference established between the two terminals it.Perhaps you're doing a lab and need to know the resistance of a resistor used in the lab.Use the widget below to determine the resistance value from the colored stripes. Household circuits are often wired with two different widths of wires: 12-gauge and 14-gauge.Most resistors have stripes or bands of colors painted on them.The colors reveal information about the resistance value.After all, if resistance occurs as the result of collisions between charge carriers and the atoms of the wire, then there is likely to be more collisions in a longer wire. Second, the cross-sectional area of the wires will affect the amount of resistance. Water will flow through a wider pipe at a higher rate than it will flow through a narrow pipe.This can be attributed to the lower amount of resistance that is present in the wider pipe.The rate at which charge flows from terminal to terminal is the result of the combined effect of these two quantities.The flow of charge through wires is often compared to the flow of water through pipes.
