An AC voltage of 220 V(rms) is applied to the primary of a 10 : 1 step-down transformer. The secondary of the transformer is centre tapped and connected to a full-wave rectifier with a load resistance. The DC voltage appearing the load is

A bistable multivibrator with a saturation voltage ±5 V is shown in the diagram. The positive and negative thresholds at the inverting terminal for which the multivibrator will switch to the other state, are
