$($a$)$ Explain why the parallel resonant circuit is generally called a tank circuit? $[$Understand$]$

$[3$M$]$

$($b$)$ A parallel resonance circuit comprises of two branches a resistor $2\backslash$Omega in series with inductor

$1$mH and $10\backslash$mu F connected to a $10$v source. Find the resonance frequency, dynamic resistance

and bandwidth. $[$Apply$][4$M$]$

$($c$)$ Analyze the above circuit if the capacitor value gets doubled with the inductor value half.
