Voltage equals current multiplied by this quantity according to Ohm's law.
The Wheatstone bridge can be used to find an unknown instance of this quantity, whose inverse is measured in siemens. The power dissipated across a conductor is equivalent to the current squared times this quantity, to which reactance must be added to find its AC equivalent, (*) impedance. Voltage equals current multiplied by this quantity according to Ohm's law. For 10 points, name this quantity measuring opposition to the flow of current.
