online electronic calculator - Ohm's law and much more

2 series capacitors calculator

Online calculator for formulas used in electronic circuit design and electrical engineering.

Basic electric calculations:

Ohm's Law, Ohm's Law with power, DC power, AC real power, LC resonant frequency, Capacitor charging/discharging, Capacitive reactance, Capacitive current + reactive power, Capacitor energy, Capacitor Δ energy, RC discharging, Inductor square pulse, Inductive reactance, Inductive current + reactive power, Inductor energy, 2 parallel resistors, 3 parallel resistors, 2 parallel inductors, 2 series capacitors, System bandwidth, Bandwidth ↔ rise time, frequency ↔ period

Wire and winding calculations:

Diameter ↔ cross section ↔ AWG, Wire resistance, Wire weight, Current density, Wire R thermal drift

Calculate 2 series capacitors: 0nF, nF, 68.65nF


This calculates the total capacitance of 2 series capacitors. It can also calculate the capacitance of the last individual capacitor to reach a target total capacitance.

Enter any 2 values, the 3rd one will be calculated:

C1: -0.1 +0.1 -1 +1 -10 +10 -100 +100
C2: -0.1 +0.1 -1 +1 -10 +10 -100 +100
Total C: -0.1 +0.1 -1 +1 -10 +10 -100 +100
Output metric prefix:   Automatic    User-selected
  C1 can't be zero or negative!
