The voltage-divider circuit shown in Fig. P3.45 is designed so that the no-load output voltage is 7/9ths of the input voltage. A d’Arsonval voltmeter having a sensitivity of 200 Ω/V and a full-scale rating of 400 V is used to check the operation of the circuit.
a) What will the voltmeter read if it is placed across the 360 V source?
b) What will the voltmeter read if it is placed across the 140 kΩ resistor?
c) What will the voltmeter read if it is placed across the 40 kΩ resistor?
d) Will the voltmeter readings obtained in parts (b) and (c) add to the reading recorded in part (a)? Explain why or why not.
