In order to pass 10% of the main current through a moving coil galvanometer of 99 ohms, the resistance of the required shunt is :

1. 9.9 Ω

2. 10 Ω

3. 11 Ω

4. 9 Ω

When a \(12~\Omega\) resistor is connected in parallel with a moving coil galvanometer, its deflection reduces from \(50\) divisions to \(10\) divisions. What will be the resistance of the galvanometer?
1. \(24~\Omega\)
2. \(36~\Omega\)
3. \(48~\Omega\)
4. \(60~\Omega\)

A voltmeter has a resistance of G ohms and range V volts. The value of resistance used in series to convert it into a voltmeter of range nV volts is :

1. nG

2. $(n-1)G$

3. $\frac{G}{n}$ 

4. $\frac{G}{(n-1)}$

Which of the following statement is wrong:

1. Voltmeter should have high resistance

2. Ammeter should have low resistance

3. Ammeter is placed in parallel across the conductor in a circuit

4. Voltmeter is placed in parallel across the conductor in a circuit
