Work out capacitors in parallel instantly with clear inputs, formula shown and shareable results.
Capacitors in parallel simply add, because they all share the same voltage and their stored charges sum. Parallel banks are used both to reach a required capacitance and to lower equivalent series resistance and inductance, which is why decoupling uses several small parts rather than one large one.
Parallel capacitance
Ctotal = C1 + C2 + C3; Q = Ctotal x V
Electrical results are planning estimates only. Verify against the applicable wiring rules (IEC 60364, BS 7671, NEC or local code) and have all installation work designed and checked by a qualified electrician.
Parallel parts divide the ripple current and reduce total ESR and ESL, giving much better high-frequency behaviour than a single large capacitor.
No. The bank is limited by the lowest-rated capacitor in it, since they all see the full voltage.
