AP EAMCET · PHYSICS · Capacitance
Two parallel plate capacitors are connected in series. Each capacitor has a plate area ' \(A\) ' and a separation ' \(d\) ' between the plates. The dielectric constant of the medium between their plates are 2 and 4 . The separation between the plates of a single air capacitor of plate area \(A\) which effectively replaces the combination is
