If the electric field E is maintained in conductor by an external source, say, a battery, then charges drift in the field and there is an electric current.
Sometimes it is convenient to introduce a quantity called conductance, which is defined as
G = 1/RThen for connection in parallel, one has G = G1 + G2 + G3 .
