Electrocalc is an app that is designed to help electronic engineers, hobbyists, and students (especially those in electronics and telecommunication engineering ) design electronic circuits. Complex electronics calculation are made easier with the app.
Resistor, capacitor, inductor, operational amplifier, 555 timer, filters and transistor circuit calculations are made easier.
The app can help an electronic hobbyist troubleshoot electronics equipment. We have worked hard in order to make designing electronics easier.
