Relationship Between Electrical Conductance And Electrical Resistance - A current flowing through a wire (or resistor). Web the unit of electric resistance is ohm (ω) r = u / i (1) where. Resistance can be calculated by measuring current via an ammeter and potential difference via a voltmeter and. Resistance is the electric property that impedes a current. R = resistance (ohm, ω) u = electrical potential (volts) i = current flow.
