## What is CCircuitCalc?

This application is intend for engineers and students who are wasting time for designing electric and electronic circuits.
The standard capacitance values based on E-series numbers are outputted in inputting necessary conditions such as combined capacitance.

Features
The calculable circuits are as follows:
- Series Circuits
- Parallel Circuits

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

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

This application can calculate current and power of each capacitor on entered ESR (Equivalent Series Resistance) values.

Attention
Because standard capacitors are used and precision of calculation is ensured, the following restrictions are set up.
- Range of capacitance value: 1pF to 100µF
- Range of capacitance ratio: 0.1 to 10
