Questions
A parallel plate capacitor with air as medium between the plates has a capacitance of . The area of capacitor is divided into two equal halves and filled with two media as shown in the figure having dielectric constant and . The capacitance of the system will now be
detailed solution
Correct option is C
CR=C1+C2=k1∈0A1d+k2∈0A2d =2×∈0A2d+4×∈0A2d Without dielectric, Cair = ∈0Ad =10μF (given) =2×102+4×102=30μFSimilar Questions
