Find the capacitance of the combination shown in figure between A and B .

Explanation

`C_3 and C_1` are in series
` C_eq = 1`
this is parallel to ` C_6 = 1 + 1 = 2`
Which is series to `= C_2 = 1 `
Which is parallel to ` C_7 = 1+1 = 2, `
Which is series to `C_3 = 1`
Which is parallel to `C_8 = 1 +1 = 2`,
Which is series to `C_4 = 1 mu F`.
