1) How does the type of wire affect resistance? - This property is called resistivity changes from material to material very low for metals 2) How does the length of wire affect resistance? - If material and other dimensions are same it increases in the same ratio as the length.[If l doubles resistance doubles] 3) How does the diameter of the wire affect resistance?- If material and other dimensions are same itdecreases in the same ratio as the square of the diameter.[If diameter doubles resistance becomes one fourth] 4) For metals, the resistivity increases linearly with temperature. 4) How does temperature affect resistance?
1) How does the type of wire affect resistance? Wires can be made of different materials , and each material has its own resistance properties, some materials have high resistance and others have low resistance. 2) How does the length of wire affect resistance? Think of it this way , when increasing the length of the wire it will be harder for the electrons to pass through, which means higher resistance it will be. 3) How does the diameter of the wire affect resistance? Small diameter wires have high resistance , because when the diameter of the wire is small it will be hard for the electrons to pass through the wire, unlikely if it has big diameter then it has small resistance because now the electrons can move easy because of its big diameter. 4) How does temperature affect resistance? Temperature also effects wires resistance, when the temperature in the wire increases the resistance will also increase, to understand why imagine your self holding a wire and buring some area in it , what will happen is the heat will melt that section and cut the wire so its like an open circuit which means very high resistance (No electrons will pass through the wire). Good Luck.
