MCQ
Two capacitors connected in parallel having the capacities ${C_1}$ and ${C_2}$ are given $'q'$ charge, which is distributed among them. The ratio of the charge on ${C_1}$ and ${C_2}$ will be
  • ✓
    $\frac{{{C_1}}}{{{C_2}}}$
  • B
    $\frac{{{C_2}}}{{{C_1}}}$
  • C
    ${C_1}{C_2}$
  • D
    $\frac{1}{{{C_1}{C_2}}}$
✓

Answer

Correct option: A.
$\frac{{{C_1}}}{{{C_2}}}$
a
(a) In parallel combination ${V_1} = {V_2}$
or $\frac{{{q_1}}}{{{C_1}}} = \frac{{{q_2}}}{{{C_2}}}$ $==>$ $\frac{{{q_1}}}{{{q_2}}} = \frac{{{C_1}}}{{{C_2}}}$
