Question

Find the equivalent capacitance between A and B in the given diagram.​

Answer 1

For figure refer the attachment

we know that a line with no capacitor in it has equal potential  

it is clear from the attachment that if no capacitor is their in the line same point can be written there

hence their are 3 capacitors between a and b but in parallel  

as given in attachment

resultant capacitance is given as

$C_{p}=C_{1}+C_{2}+C_{3}\\C_{p}=3+5+7\\C_{p}=15\mu F$

hope it helps
