MCQ
When is the effective capacitance of a capacitor increased?
  • A
    When the capacitors are connected in series.
  • B
    When the capacitors are randomly connected.
  • When the capacitors are connected in parallel.
  • D
    When the capacitors are connected in series and parallel simultaneously.

Answer

Correct option: C.
When the capacitors are connected in parallel.

The effective capacitance of a capacitor is increased when the capacitors are connected in parallel. When the capacitors are connected in parallel, the equivalent capacitance is given by:
$C_p=C_1+C_2+C_3+\ldots \ldots$
When the capacitors are connected in parallel, the potential difference across each capacitor is the same.
