Question

Find the equivalent capacitance across A and B.
.
A. `(35)/6muF`
B. `(25)/6 muF`
C. `15 mu F`
D. none of these

Answer 1

Correct Answer - A
Circuit can be redrawn as follows:
.
Now, `V_(x)V_(y)`. Hence
`(25 muF)/(5muF)=(7muF)/(2 muF)`
`C_(eq)=((5xx25)/(5+25))+((10xx2)/(100+25))=(35)/6=(35)/6 muF`.
