The electrical resistance of an electrical conductor is a measure of the difficulty to pass an electric current through that conductor. It is measured in Ohms and the relation between resistance ($$R$$), current ($$I$$) and electrical potential ($$V$$) is Ohm's law: $$V = IR$$. Ohm's law says that a larger voltage makes more current flow if resistance is fixed. Or if resistance is lower at the same voltage, more current will flow.
