The correct answer is option 3):(3.535)

Concept:

Resonant frequency for a series RLC circuit is given by

: ω0=

Bandwidth for a series RLC circuit is given by

 B.W.= 

Also, the quality factor is given by

Calculation:

Given that, R = 4 Ω, L = 4 mH, C = 25 μF

For the given RLC network, the resonant frequency will be:

ω0=

=3535 Hz

 B.W.= 

= 1000

= 3.535
