Find the equivalent capacitance across `A & B`

Options

A. `(28)/(3)muF`
B. `(15)/(2) muF`
C. `15 muF`
D. None

Answer

B

Explanation

Circuit can be redrawn as

Now `V_(x) = V_(y)`
Hence`(35 muF)/(10 muF) = (7 muF)/(2 muF)`
`C_(eq) = ((7 xx 35)/(7 + 35)) + ((10 xx 2)/(10 + 2)) = (35)/(6) + (10)/(6) = (45)/(6)`
`C_(eq) = (15)/(2) muF`
