# A parallel plate capacitor is made by stacking n equally spaced plates connected alternatively. If the capacitance between any two adjacent plates is 'C' then the resultant capacitance is (a) (n+1) C(b) (n -1 )C(c) nC(d) C

(b) As n plates are joined, it means (n-1) combination joined in parallel.

? resultant capacitance = (n – 1 ) C

Each plate is taking part in the formation of two capacitors except the plates at the ends. These capacitors are in parallel and n plates form (n -1) capacitors.Thus, equivalent capacitance between A and B = (n -1) C

We know that when we connect 4 capacitors each of capacitance Calternately,it performs like 3 capacitors in parallel i.e.(4-1)C.So n capacitors will be equivalent to (n-1)C.

Dear student,

When n equally spaced plates are stacked alternatively, a total of (n – 1) capacitors are formed which are all in parallel.
Hence, The equivalent capacitance will be
Ceq = (n – 1) C
Hence, option (b) will be correct.

Thanks and regards,
