Question

Problem 3.49 6 of 13 A Review Constants A 200 kn resistor is connected from the 100 V terminal to the common terminal of a dual-soal voltmeter, as shown in Figure 1). This modified Voltmeter is then used to measure the voltage across the 600 kronistor in the circuit in (Figure 2) Part A What is the reading on the 820 V scale of the meter? Assume that both scales of the given dual scale voltmeter were recalibrated when the 200 kn resistor was connected to its terminals, so 100 V and 820 V are not actually the full- scale readings of the modified voltmeter Express your answer to three significant figures and include the appropriate units.

Answer 1

Mere resistance Rm= 100 mV - 502 amA So Greutis so 49,95 + 50 50kr 360k ook { book ok 300 V 2001150 dooxjo 250 Hok 260 +40 = 400 K. 600/400 foox 400 1000 = 240K 240 +60e 300 k so Voltage is Vm= 240 V.. Part A Vm= 240 V Pout B. actuall deltage. V. = 600 x 300 = 600710 272.7 Coor=Vr-Vm Up X 600 272.7-240 X100 272.7 Error 12.1 % CS Scanned with CamScanner 1
