Answer / k.prakashchandra

If you want to measure ER of particular electrode ,you have
to disconnect it , to avoid the influence of other electrode
connected to the same equipment.If the cables are connected
in parallel ,the load sharing is inverse to the resistances
of cables so that the voltage drops in the cables are equal
