AIEEE 2005 | Current Electricity Question 330 | Physics

Two voltmeters, one of copper and another of silver, are joined in parallel. When a total charge $$q$$ flows through the voltmeters, equal amount of metals are deposited. If the electrochemical equivalents of copper and silver are $${Z_1}$$ and $${Z_2}$$ respectively the charge which flows through the silver voltmeter is

$${q \over {1 + {{{Z_2}} \over {{Z_1}}}}}$$

$${q \over {1 + {{{Z_1}} \over {{Z_2}}}}}$$

$$q{{{Z_2}} \over {{Z_1}}}$$

$$q{{{Z_1}} \over {{Z_2}}}$$
