| 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 (K), the reading of current will be: [AIPMT 1999] |
 |
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 \[{{A}_{2}}\]
Correct Answer: D
Solution :
Initially there is no DC current in inductive circuit and maximum DC current in capacitive circuit. Hence, the current is zero in \[{{A}_{2}}\] and maximum in \[{{A}_{1}}\].
