Which of the following components of an $LCR$ circuit,with $ac$ supply,dissipates energy?

In $AC$ circuits,a choke coil is preferred over resistors because:

If we increase the frequency of an $a.c.$ supply,then inductive reactance

If the capacitance of a pure capacitor in a $DC$ circuit is $1 \ F$,then what will be its capacitive reactance?

An alternating voltage $E = 200 \sqrt{2} \sin(100 t) \text{ V}$ is connected to a $1 \mu\text{F}$ capacitor through an $A.C.$ ammeter. The reading of the ammeter shall be: (in $\text{ mA}$)

The reactance of an inductor at $50 \, Hz$ is $10 \, \Omega$. The reactance of it at $200 \, Hz$ is
