Emma wanted to investigate the resistance of a sample of a material.
Graph 1 shows how the resistance changes with length.
(the graph in the photo)
Length in centimetres
(i) The current through a 20 cm length of conducting putty was 0.15 A.
Use Graph 1 to find the resistance of a 20 cm length of conducting putty.
Resistance = . ohms
