What is the equivalent capacitance when a capacitor is connected in parallel with a conducting wire?
Suppose each capacitor has a capacitance 1 microfarad.We can easily notice the vertical axis of symmetry.Hence we can isolate the central junction.
I'm getting the equivalent capacitance of upper branch as as 3/8 microfarad using formula for capacitors in series i.e. 1/(1/1+1/1.5+1/1) microfarad .Therefore capacitance of the whole circuit is 3/8+3/8+0=3/4 microfarad.
However according to my textbook the answer is 2 microfarad.Where am I going wrong?
