Answer» Correct Option (a) 3 μF Explanation The last three capacitors on teh right. Each of capacitance C = μF are in series and are equivalent to a capacitance C' given by 1/C' = 1/9+1/9+1/9 = 1/3 or C' = 3μF Since C' is in parallel with C₁, the equivalent capacitance of the last part of the network is C" = C' + C₁ = 3 + 6 = 9 μF.

Answer»

Correct Option (a) 3 μF

Explanation

The last three capacitors on teh right. Each of capacitance C = μF are in series and are equivalent to a capacitance C' given by

1/C' = 1/9+1/9+1/9 = 1/3

or C' = 3μF

Since C' is in parallel with C₁, the equivalent capacitance of the last part of the network is C" = C' + C₁ = 3 + 6 = 9 μF.
