Question: A volt-ratio box is designed with a resistance 100 Ω/V. it has input terminals of 300V, 150V and 75 V, and an output terminal of 1.5 V which is connected to the potentiometer. Supposing a voltage of 270V is connected to the 300 V terminals, what is voltage indicated by the potentiometer and what is the power consumption under null conditions?
Answer:
