From the result, we can see that the values that we got may be differ from the marked values but not much. The result can be agreed with the tolerance range used in the investigation according to KVL and KCL, Vs= Vr1 +Vr2 and Is = Ir1+Ir3 respectively. From the series and parallel Circuits, we can see that the current for resistors in series still have the same values but seperate in voltage but in parallel they seperated in the current but the voltage remain the same .
