Question

Which relation gives the charge on one capacitor in a parallel combination when the common voltage is \[V\]?

विकल्प

• \[Q_i=C_i+V\]

• \[Q_i=\frac{C_i}{V}\]

• \[Q_i=C_iV\]

• \[Q_i=\frac{V}{C_i}\]

Answer 1

The charge on a capacitor is its capacitance multiplied by the voltage across it. In parallel, each capacitor has the same voltage \[V\], so \[Q_i=C_iV\].
