This circit shows a number of series resistances connocted in series and also connected with them a voltage source .
we observe from this simulation
The same current flows through all the resistances.
The voltage of the supplier is distributed among the loads with respect to resistance value as V=IR
The equivilant circuit to this circuit as shown have a resistance that equals 70000 ohms
There fore the equivilant resistance of the circuit = 7000 ohms = summation of each load resistance
