dude please refer to the attachment....

Let the capacitors between AC , CB , AD and BD be named as P , Q , R and S respectively

using the property of WHEATSTONE BRIDGE.........

In this circuit....

P = 5 uF

Q = 5 uF

R = 5 uF

S = 5 uF

●●》P/R = (5uF) / ( 5uF) = 1

●●》Q/S = ( 5uF) / (5uF) = 1

■ for a balanced wheatstone

bridge...

=> P/R = Q/S

in this given circuit,

P/R = Q/ S = 1

thus, it is a balanced wheatstone bridge.....

and hence, the capacitor of 10 uF can be removed or not included in the calculation of equivalent capacitance......

for series combination of capacitance

1/ Cseries = 1/Ca + 1/Cb

for parallel combination of capacitance

1/C parallel = Ca + Cb

The capacitor between AC and CB are in series combination.....

thus, Equivalent capacitance c =>

1/ Cc = 1/ Cac + 1/ Cbc

=> 1/ Cc = 1/ 5uF + 1/ 5uF

=> 1/ Cc = (1+1)/ 5uF

=> Cc = (5/2) uF

The capacitor between AD and DB are in series combination .....

Thus, the equivalent capacitance d =>

1/ Cd = 1 / Cad + 1 / Cdb

=> 1/ Cd = 1/ 5uF + 1/ 5uF

=> 1 / Cd = (1+1)/5uF

=> Cd = (5/2) uF

The capacitance C and D are in parallel combination......

therefore, the equivalent capacitance ab =>

Cab = Cc + Cd

=> Cab = 5uF/2 + 5uF/2

=> Cab = 10uF/2 = 5 uF

The capacitors of capacitance 5uF and 5 uF are in series combination .....

thus,,

the equivalent capacitance of whole

circuit { Ceq} =>

1/ C eq = 1/ C ab + 1/ 5 uF

=> 1/ C eq = 1/5 uF + 1/ 5uF

=> 1/ C eq = (1+1)/5 uF

=> C eq = (5/2)uF

ANSWER: -

equivalent capacitance =

2.5uF
