Three moving iron type voltmeters are connected as shown below. Voltmeter readings are $$V,$$ $${V_1}$$ and $${V_2}$$ , as indicated. The correct relation among the voltmeter readings is A
$$V = {{{V_1}} \over {\sqrt 2 }} + {{{V_2}} \over {\sqrt 2 }}$$
B
$$V = {V_1} + {V_2}$$
C
$$V = {V_1}{V_2}$$
D
$$V = {V_2} - {V_1}$$

An ammeter has a current range of $$0$$-$$5A,$$ and its internal resistance is $$0.2\Omega$$. In order to change the range to $$0$$-$$25$$ $$A$$ we need to add a resistance of
A
$$0.8\,\Omega$$ in series with the meter
B
$$1.0\,\Omega$$ in series with the meter.
C
$$0.04\,\Omega$$ in parallel with the meter
D
$$0.05\,\Omega$$ in parallel with the meter
