Options:
  • A \(\frac{\mathrm{VC}_1}{\left(\mathrm{C}_1+\mathrm{C}_2\right)}\)
  • B \(\mathrm{v}\left(1+\frac{\mathrm{C}_2}{\mathrm{C}_1}\right)\)
  • C \(\mathrm{V}\left(1+\frac{\mathrm{C}_1}{\mathrm{C}_2}\right)\)
  • D \(\frac{\mathrm{VC}_2}{\left(\mathrm{C}_1+\mathrm{C}_2\right)}\)

The correct answer is: \(\frac{\mathrm{VC}_1}{\left(\mathrm{C}_1+\mathrm{C}_2\right)}\)
Charge \(\mathrm{Q}=\mathrm{C}_1 \mathrm{~V}\)
Total capacity of combination (parallel)
\(\mathrm{C}=\mathrm{C}_1+\mathrm{C}_2\)
\(\text {P.D. }=\frac{\mathrm{Q}}{\mathrm{C}}=\frac{\mathrm{C}_1 \mathrm{~V}}{\mathrm{C}_1+\mathrm{C}_2}\)
