Question

In the given circuit, ammeters $A_1$ and $A_2$ are ideal and the voltmeter $\left(V\right)$ is having very large resistance. In the steady state reading of ammeters $A_1$, $A_2$ and voltmeter $\left(V\right)$ will be respectively

• A. $0,\frac{\epsilon }{2R}$ and $\frac{\epsilon }{2}$
• B. $0,\frac{\epsilon }{R}$ and $\frac{\epsilon }{2}$
• C. $0,\frac{\epsilon }{2R}$ and $\frac{5\epsilon }{2}$
• D. $0,\frac{\epsilon }{2R}$ and $\frac{3\epsilon }{2}$

Answer 1

The correct option is A $0,\frac{\epsilon }{2R}$ and $\frac{\epsilon }{2}$

in steady state capacitor act as open circuit hence current through $A_1$ is 0

voltage across the resistor is $ϵ$$

$ϵ=i\times 2R$

$i=\frac{ϵ}{2R}$
