152896 A galvanometer has resistance of $100 \Omega$ and a current of $10 \mathrm{~mA}$ produces full scale deflection in it. The resistance to be connected to it in series, to get a voltmeter of range 50 volt is

1 $4900 \Omega$
2 $4000 \Omega$
3 $4600 \Omega$
4 $3900 \Omega$

152897 The range of an ammeter of resistance ' $G$ ' can be increased from ' $I$ ' to ' $\mathrm{nI}$ ' by connecting

1 a series resistance of $\frac{\mathrm{G}}{\mathrm{n}+1} \Omega$
2 a shunt of $\frac{\mathrm{G}}{\mathrm{n}+1} \Omega$
3 a series resistance of $\frac{\mathrm{G}}{\mathrm{n}-1} \Omega$
4 a shunt of $\frac{\mathrm{G}}{\mathrm{n}-1} \Omega$

152898 A circuit contains an ammeter, a battery of 30 $V$ and a resistance of $40.8 \Omega$ all connected in series. If the ammeter has a coil of resistance $480 \Omega$ and a shunt of $20 \Omega$, the reading in the ammeter will be

1 $0.25 \mathrm{~A}$
2 $1 \mathrm{~A}$
3 $0.5 \mathrm{~A}$
4 $2 \mathrm{~A}$

152899 Figure shows a potentiometer. Length of the potentiometer wire $A B$ is $100 \mathrm{~cm}$ and its resistance is $100 \Omega$. EMF of the battery $E$ is $2 \mathrm{~V}$. A resistance $R$ of $50 \Omega$ draws current from the potentiometer. What is the voltage across $R$ when the sliding contact $C$ is at the mid-point of $\mathrm{AB}$ ?

1 $2 / 3 \mathrm{~V}$
2 $1 \mathrm{~V}$
3 $4 / 3 \mathrm{~V}$
4 $3 / 2 \mathrm{~V}$
