perl · Answer

The total capacitance of capacitors in series is equal to the reciprocal of the sum of the reciprocals of their individual capacitances:

haseeb96 · Answer

yes

perl · Answer

$$
\Large  \frac{1}{C_\mathrm{total}} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3}

$$

haseeb96 · Answer

but how can i calculate the total current ?

perl · Answer

you can plug in the individual capacitances in amps

haseeb96 · Answer

how?
can u give me an example?
