This application is intend for engineers and students who are wasting time for designing electric and electronic circuits.
The standard resistance values based on E-series numbers are outputted in inputting necessary conditions such as input voltage, output voltage, current and so on.

The calculable circuits are as follows:
- Voltage Dividers (Inputting output voltage or resistance ratio)
- Series Circuits
- Parallel Circuits
- Combination Circuits

In the Voltage Dividers, resistance values are calculated in entering input voltage, output voltage or resistance ratio, and current into input boxes, besides, the most suitable resistance values are calculated in selecting priority whether Normal or Vout.

In the Series Circuits, Parallel Circuits and Combination Circuits, divided resistance values are calculated in entering a combined resistance value into an input box.

Calculated resistance values are displayed with the following E-series number specified either.
E6, E12, E24, E48, E96

This application is able to calculate current and power of each resistor on calculated resistance values.

Because standard resistors are used and precision of calculation is ensured, the following restrictions are set up.
- Range of resistance value: 1Ω ~ 10MΩ
- Range of resistance ratio: 0.1 ~ 10

What’s New

Version 2.3.0
