Does diameter of wire affect current?
A larger diameter wire will carry more current than a small diameter will. A longer wire will eventually carry less current, because the resistance increases as the length increases. A shorter wire can carry more current than a longer wire.
How does wire size affect current?
Unfortunately, size does matter. The most basic explanation on why wire gauge matters is because the thinner a wire is (higher gauge) the more resistance there will be to the flow of current. More resistance means more energy loss, which means weaker/less reliable detections.
Does the thickness of wire affect the ability of the wire to conduct heat?
Because it depends on the resistance of each wire and how much power is applied to each wire. If the wires are made of the same material and the same amount of current is applied to each wire then the thin wire will heat up more. R = resistance of thick wire.
What are the factors that affect the electrical resistance of a wire?
There are several factors that affect the resistance of a conductor;
- material, eg copper, has lower resistance than steel.
- length – longer wires have greater resistance.
- thickness – smaller diameter wires have greater resistance.
- temperature – heating a wire increases its resistance.

How does the thickness of wire gauge affect an electrical system?
The wire gauge refers to the THICKNESS of the wire. As such, lesser the thickness of a wire, higher will be its resistance and vice-versa. Consequently, due to higher resistance, flow of current will be reduced and voltage drop across the length of the wire will increase.
Does wire size matter for voltage?
As others have stated, the voltage of the appliance/circuit has no bearing on the size (gauge) of the wire. Voltage dictates the quality of the insulation of a wire and most (power) wire we encounter will be rated for 600 Volts.
How does the thickness of the wire affect the heat produced?
The amount of heat produced in a Wire depends on its material, length and thickness. The relationship between resistance and wire length is directly proportional. The resistance of thin wire is greater than the resistance of a thick wire because a thin wire has fewer electrons to carry the current.
