Question

In a circuit inductance $L$ and capacitance $C$ are connected as shown in figure. $A_1$ and $A_2$ are ammeters.
When key $K$ is pressed to complete the circuit, then just after closing key $\left(K\right)$, the readings of $A_1$ and $A_2$ will be

• A. zero in both $A_1$ and $A_2$
• B. maximum in both $A_1$ and $A_2$
• C. zero in $A_1$ and maximum in $A_2$
• D. maximum in $A_1$ and zero in $A_2$

Answer 1

The correct option is D maximum in $A_1$ and zero in $A_2$

$\text{Initially there is no D.C current in inductive circuit and maximum D.C}$
$\text{current is in capacitive current. Hence, the current is zero in}$
$A_2\text{and maximum in}{A}_1$
