Q22. Describe resistance, list 4 factors affecting resistance?
Q23. A conductor has a length of 2.0 m and a radius of 3.0 mm. If the resistance is R = 100 S, calculate the new resistance if the same material has:
a) length = 6.0 m and r = 6.0 mm
b) length = 1.0 m and r = 1.0 mm

resistance is directly proportional to the length of the conductor
resistance is inversely proportional to the area of cross section
resistance doesn't depends on the dimensions of the conductor
resistivity depends on the nature of its material
