In the given circuit, ammeters \[{{A}_{1}}\] and \[{{A}_{2}}\] are ideal and the voltmeter (V) is having very large resistance. In the steady state reading of ammeters \[{{A}_{1}},{{A}_{2}}\] and voltmeter (V) will be respectively          

A) \[0,\frac{\varepsilon }{2R}\] and \[\frac{\varepsilon }{2}\]

B)        \[0,\frac{\varepsilon }{R}\] and \[\frac{\varepsilon }{2}\]

C) \[0,\frac{\varepsilon }{2R}\] and \[\frac{5\varepsilon }{2}\]

D) \[0,\frac{\varepsilon }{2R}\] and \[\frac{3\varepsilon }{2}\]

Correct Answer: A

Solution :

[a] In steady state, capacitor behave as an open circuit. \[\therefore \]  Reading of \[{{A}_{1}}=0\] \[I=\varepsilon /2R=\]reading of ammeter \[{{A}_{2}}\]
