# Investigate factors affecting resistance wire

Text preview physics coursework- ohm's law aim: to investigate the factors of affecting the resistance of a wire in this experiment i will be using a metal nichrome wire to show the resistance when the length and width is changed. Start studying unit 1 physics practicals learn vocabulary, use an air track to investigate factors affecting uncertainties & work done against air resistance . What are the factors that affect resistance of a material/wire the resistance of a wire, what are the factors affecting resistance of a resistor. The resistance of a typical conducting wire is low when temperature is low and high when temperature is high the increase in resistance alongside temperature is due to an increase in energy of the wire atoms, which cause them to vibrate more and impede the path of the electrons flowing through.

Dc resistance of a wire is determined by the what factors can lower the electrical resistance of a what are the factors that affect resistance of a . What are the four factors that affect the resistance of a wire factors affecting resistance of a wire its elemental make up,its diameter and length. The four factors that affect the resistnce of a wire aim: to investigate how the length of a nichrome wire can factors affecting the resistance of a wire . The probes and alligator clips have a resistance, and would need to be subtracted from the measurement of the total resistance to give the resistance of the copper wire that was to be measured.

Factors affecting resistance are followings [r= (ρl/a)] (i)larger the length, higher the value of resistance of wire (ii) lesser the resistivity of the material of wire, lesser is the resistance of the wire ie resistance depends on the nature of the material. Why does the thickness of a wire affect resistance the resistance of a wire depends on 3 parameters: you have to consider these factors. I am going to investigate what factors affect the resistance of a wire to begin with i am going to investigate which materials put up the highest . This is why i have chosen to investigate this as the second factor interested in factors affecting resistance of wire lab background knowledge.
