For engineers and students who design electric and electronic circuits

The calculable circuits are as follows:

 

1. Series Circuits

2. Parallel Circuits

 

All circuits are capable of calculating up to 4 capacitors.

  • Calculate divided capacitance values in entering a combined capacitance values
  • Display capacitance values corresponded to a selected E-series number (E6 ~ E24)
  • Only tap on a unit button directly when a unit of capacitance is changed (pF or nF or µF)
  • Correspond to specified capacitance values of less than 10pF by a selectable switch
  • Display current and power of each capacitor when input voltage is entered in the detail page

The calculable series circuits are 2, 3 and 4 capacitors.

In this page, display calculated C0, and calculate current and power of each capacitor when input voltage (Vin) and ESR (Equivalent Series Resistance) values.

 

Procedure of current and power calculation

 

1. Enter input voltage (Vin) in the frame and select unit button (µV or mV or V)

2. Enter ESR (Equivalent Series Resistance) values into each symbol (C1 or C2 or C3)

3. Display calculate current and power of each capacitor

* When you want to view voltage value of each capacitor, please push each symbol (P1 or P2 or P3).

* C1, C2 and C3 have set 100mΩ as ESR.

Because standard capacitors are used and precision of calculation is ensured, the following restrictions are set up.

  • Range of capacitance value: 1pF ~ 100µF

"< 1pF" is displayed when capacitance value is less than 1pF, "> 100µF" is displayed when capacitance value is more than 100µF.

  • Range of capacitance ratio (C1/C2 or C1/C3 or C1/C4 or C2/C3 or C2/C4 or C3/C4) : 0.1 ~ 10

It has restricted so that it may become the above range automatically by the input text box.
