Question

For two capacitors in series, which expression gives the voltage across the first capacitor?

Options

• \[V_1=(C_1+C_2)V\]

• \[V_1=\frac{C_2}{C_1+C_2}\cdot V\]

• \[V_1=\frac{C_1}{C_1+C_2}\cdot V\]

• \[V_1=\frac{C_1+C_2}{C_2}\cdot V\]

Answer 1

For two series capacitors, the voltage across the first is proportional to the other capacitor's capacitance. The relationship is \[V_1=\frac{C_2}{C_1+C_2}V\].
