Question

Two parallel plate of area A are separated by two different dielectrics as shown in the figure. The net capacitance is –

• A. $\frac{4\varepsilon_{0}A}{3d}$
• B. $\frac{3\varepsilon_{0}A}{4d}$
• C. $\frac{2\varepsilon_{0}A}{d}$
• D. $\frac{\varepsilon_{0}A}{d}$

Answer 1

Answer: (A)

$\frac{4\varepsilon_{0}A}{3d}$

Answer 2

C = $\frac { \varepsilon _ { 0 } \mathrm {~A} } { \frac { \mathrm { t } _ { 1 } } { \mathrm { k } _ { 1 } } + \frac { \mathrm { t } _ { 2 } } { \mathrm { k } _ { 2 } } }$
