Question

Which formula gives the equivalent capacitance of capacitors in parallel?

Options

• \[\frac{1}{C_P}=C_1+C_2+C_3+\cdots\]

• \[C_P=C_1C_2C_3\]

• \[C_P=C_1+C_2+C_3+\cdots\]

• \[\frac{1}{C_P}=\frac{1}{C_1}+\frac{1}{C_2}+\frac{1}{C_3}+\cdots\]

Answer 1

The parallel formula is the sum of the individual capacitances. This follows because the voltage is the same across each capacitor while their charges add.
