The resistance of a component depends on an electrical property of the material that it is made from. This property is called resistivity.
Copper 1.7 x 10-8 Ohm- metres.
Iron 1 x 10-7 Ohm- metres.
Graphite 10-5 Ohm- metres (very variable).
Silicon 105 Ohm- metres.
Paraffin wax 1015 Ohm- metres.
Porcelain 1020 Ohm- metres.
Resistance also depends on the physical dimensions of the component.
What is the resistance of 100m of copper wire with a cross sectional area of 1.5mm2.
