Description : What do you mean by frequency response of an amplifier?

Description : State the need of multistage amplifier. Draw frequency response of R-C coupled amplifier.

**Answer :** The need of multistage amplifier The voltage (or power) gain, obtained from a single stage small signal amplifier, is limited. Therefore, it is not sufficient for all practical applications. Therefore, in ... to use a MULTISTAGE AMPLIFIER . Frequency response of R-C coupled amplifier.

Description : In a series R-C circuit, with the increase in frequency, current (A) Reduces (B) Increases (C) Does not change (D) Becomes zero

**Answer :** In a series R-C circuit, with the increase in frequency, current Increases

Description : A series R-L-C Circuit has a resonant frequency of 1000 Hz. If the values of R, L and C are doubled, the new resonant frequency is

**Answer :** A series R-L-C Circuit has a resonant frequency of 1000 Hz. If the values of R, L and C are doubled, the new resonant frequency is 500 Hz
