Favtors That Affect Resistance

Question 1

Type of material

Answer 1

Materials such as copper And silver a very good conductors of electricity because they allow the
electrons to flow easily

Question 2

Cross-sectional area

Answer 2

Wires with a smaller diameter restrict the flow of electrons and therefore have a higher resistance. Larger wire is allowed for more electrons to flow through and therefore have a low resistance

Question 3

Length

Answer 3

The longer the wire the higher the resistance the shorter the wire the lower the resistance this is because electrons have to travel through more material in longer wire

Question 4

Temperature

Answer 4

The higher the temperature the higher the resistance this is because as you heat the conductor the Adam and electrons vibrate more which makes it more likely for the particles to bump into one another more randomly slowing the flow down
