Features & Capabilities

All-in-one electronics app with calculators, simulators, and component guides. Perfect for engineers, students, and makers.

Electrohelper is carefully designed to address the need for electronic engineers and electronics hobbyists in designing an electronic circuit. The app contains the electronic components reference section, electronic circuit reference section, and electronic circuit calculation section. Tedious electronic circuit calculation such as Butterworth, Sallen-Key, Chebychev, and Bessel filter is made easier with the app.

User Reviews

as usual, it doesnt include the most essential thing about transformers: the EMF equation. [V=√2πfNAB(max)] which is an extremey ignorant thing to do. education doesnt come from blindly repeating phrases! according to the "equations" you have in your "transformer calculator": i can use 1 turn on the primary side of a mains transformer and use 10 turns on the seconday to get 10 times as much voltage! but when you say this to these people, they blindly repeat "noo! low reactance makes short!" without knowing what are they talking about! like sheep!!! they cant explain why you cant use 1 turn on the primary! and when someone wants to know why, they will have a hard time searching for a reasonable reason. the review is getting too long, so if YOU want to know the reason why you cant use 1 turn (and why MOTs saturate), copy the equation and ask google why you cant use 1 turn, then tell him to explain using this equation, then explain the equation itself. and dont forget to tell him what type of core you are using (iron or ferrite (because this equation works for high frequencies, too!)) V = √2×π×f×N×A×B
