Is given by the sum of the resistance ok and so to have a license and CDs than effectively it's the same as if there was a single resistor values the sum of all the resistance Nootrology okay you can look at the course notes for a proof of our operation of this of this fact a similarly if I have a resistances and Powell soul of let me call them conductance’s of conductance is up are the reciprocal of a Dr assistance I for instance measure in homes conductance the measured in miles image not okay so I'll for to the conductance love.
