- The circuit shown in the figure contains an inductor L, a capacitor \(C_0\), a resistor\( R_0\) and an ideal battery. The circuit also contains two keys \(K_1\) and \(K_2\). Initially, both the keys are open and there is no charge on the capacitor. At an instant, key \(K_1\) is closed and immediately after this the current in \(R_0\) is found to be \(I_1\). After a long time, the current attains a steady state value \(I_2\). Thereafter,\( K_2\) is closed and simultaneously \(K_1\) is opened and the voltage across \(C_0\) oscillates with amplitude \(C_0\) and angular frequency \(\omega_0\).
Match the quantities mentioned in List-I with their values in List-II and choose the correct option.List-I List-II P The value of \(I1\) in Ampere is I \(0\) Q The value of I2 in Ampere is II \(2\) R The value of \(\omega_0\) in kilo-radians/s is III \(4\) S The value of \(V_0\) in Volt is IV \(20\) 200 - JEE Advanced - 2024

Concepts Used:
Specific Heat Capacity
Specific heat of a solid or liquid is the amount of heat that raises the temperature of a unit mass of the solid through 1°C.
Molar Specific Heat:
The Molar specific heat of a solid or liquid of a material is the heat that you provide to raise the temperature of one mole of solid or liquid through 1K or 1°C.
Specific Heat at Constant Pressure or Volume:
The volume of solid remains constant when heated through a small range of temperature. This is known as specific heat at a constant volume. It is denoted as CV.
The pressure of solid remains constant when heated through a small range of temperature. This is known as specific heat at constant pressure which can be denoted as CP.
