A practical capacitor is a type of capacitor that consists of two sets of semicircular aluminum or brass plates separated by a dielectric material. Practical capacitors can be constructed by interleaving the plates with two dielectric layers and rolling them up. By staggering the plates, connections can be made to one plate at each end of the roll.

Why is a coupling capacitor used in AC circuits?
A coupling capacitor is used in AC circuits as it allows alternating current to pass through but not the DC current.
