# Formula Parallel connection of capacitors (total capacitance)

## Total capacitance

Unit

It is the total capacitance of all $$n$$ capacitors connected in parallel. In a parallel circuit, the capacitances of the capacitors add up.

Capacitance is a characteristic quantity of the capacitor and tells how many charges must be brought onto the capacitor to charge the capacitor to the voltage $$1 \, \mathrm{V}$$.

## Partial capacitances

Unit
Capacitances of individual capacitors connected in parallel.

Example: Two capacitors are connected in parallel. They have the values $$C_1 = 100 \, \mu\mathrm{F}$$ and $$C_2 = 300 \, \mu\mathrm{F}$$. The total capacitance is thus:$C ~=~ C_1 + C_2 ~=~ 100 \, \mu\mathrm{F} + 300 \, \mu\mathrm{F} = 400 \, \mu\mathrm{F}$
