CBSE BoardEnglish MediumSTD 12 SciencePhysics2. Electric potential and capacitance1 Mark
MCQ
A parallel plate capacitor is made by stacking $n$ equally spaced plates connected alternately. If the capacitance between any two plates is $C$ then the resultant capacitance is
  • A
    $C$
  • B
    $nC$
  • ✓
    $(n - 1)C$
  • D
    $(n + 1)C$
✓

Answer

Correct option: C.
$(n - 1)C$
c
(c) The given arrangement becomes an arrangement of $(n - 1)$ capacitors connected in parallel. So ${C_R} = (n - 1)C$
