An infinite ladder of capacitors each 1m...

An infinite ladder of capacitors each `1muF` is made as shown in the figure. The capacitance between A and B (in `muF`) is - (Hint: Solve similarly as we have done for resistors)

A

1

B

`1.3`

C

`1.6`

D

Zero

Verified by Experts

The correct Answer is:

C

Use shortcut method
First two blocks

`C_("Approx")=(3)/(2)=1.5muF`
`:.C_(eq)` is slightly more than 1.5`muF`
So 1.6`muF` is correct answer.
