The voltage-divider circuit shown in Fig. P3.45 is
Chapter 3, Problem 3.45(choose chapter or problem)
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 dArsonval voltmeter having a sensitivity of 100 /V and a full-scale rating of 200 V is used to check the operation of the circuit. a) What will the voltmeter read if it is placed across the 180 V source? b) What will the voltmeter read if it is placed across the 70 k resistor? c) What will the voltmeter read if it is placed across the 20 k 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. Figure P3.4
