Questions
Parallel plate capacitor is constructed using three different dielectric materials as shown in fig.
The parallel plates, across which a potential difference is applied are of area A cm2 and separated by a distance d cm. The capacitance across AB is
detailed solution
Correct option is A
C1=K1ε0A2d=K2ε0AdC2=K2ε0A2d2=K2ε0Adand C3=K3ε0AdNow C=C1+C2C3C2+C3Similar Questions
