1. An identifier may start with an underscore.
2. An identifier may end with an underscore.
3. If is a valid identifier.
4. The number of significant characters in and identifier is implementation dependent.

Assertion (A): A series RLC circuit resonates when excited by variable frequency source.

Reason (R): Resonant frequency is geometric mean of half power frequencies.

1. The reduction in h₁₂ and Miller capacitance result in negligible reverse internal feedback.
2. A's is large loads cannot be connected.
3. As a narrow band amplifier, it provides small range of c_μ is reduced.
4. As a narrow band amplifier it provides small range of frequencies parameters the effect of c_μ reduces.
