The voltmeter reads `40 V` across `60 Omega` resistance. The resistance of voltmeter is.
.

The voltmeter shown in the figure reads 10V across 40 omega . The resistance of voltmeter is

The voltmeter shown in fig, reads 6V across the 60 Omega resistor. Then the resistance of the voltmeter is-

The voltmeter shown in figure reads 18V across the 50(Omega) resistor. Find the resistance of the voltmeter.

The voltmeter shown in figure reads 18V across the 50(Omega) resistor. Find the resistance of the voltmeter.

The voltmeter shown in figure reads 18V across the 50(Omega) resistor. Find the resistance of the voltmeter.

The voltmeter in figure has a resistance of 200 Omega . The reading of voltmeter is

In Fig. 6.59 , when an ideal voltmetre is connected across 4000 Omega resistance, it reads 30 V . If the voltmeter is connected across 3000 Omega resistance, it will read

In Fig. 6.59 , when an ideal voltmetre is connected across 4000 Omega resistance, it reads 30 V . If the voltmeter is connected across 3000 Omega resistance, it will read
