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. The app contains the following calculators. • Resistor color code • Resistance calculator • Resistors in series • Resistors in parallel • Capacitors in series • Capacitors in parallel • Capacitance of a capacitor calculator • Parallel plate capacitor calculator • Capacitive reactance calculator • Ceramic capacitor code • Polyester capacitor code • SMD resistor code • Toroidal inductor winding calculator • Inductor winding calculator • Air core inductor winding calculator • Adjustable voltage regulator calculator • Zener diode voltage regulator calculator • Bipolar junction transistor (BJT) amplifier analysis calculator • LR filter calculator • Parallel RLC calculator • Transformer winding calculator • 555 timer astable multivibrator calculator • 555 timer monostable multivibrator calculator • Op-amp inverting amplifier calculator • Op-amp noninverting amplifier calculator • Op-amp difference amplifier calculator • Sallen-Key single-pole filter calculator • Sallen-Key double-pole filter calculator • Butterworth passive filter calculator • Chebychev passive filter calculator • Bessel passive filter calculator • Active filter calculator • RC passive filter calculator • Inductive reactance calculator • Series LRC circuit calculator • Resistor voltage divider calculator • Wheatstone bridge calculator • Charging/Discharging a capacitor calculator • Charging/Discharging an inductor calculator • Resistivity calculator • PCB trace width calculator • Attenuators calculator • Microstrip calculator • Wave guide calculator • Electrical power calculator • Decibel calculator • Alternating current (AC) calculator • Ohms law calculator • Delta -> Star transformation • Star-> Delta transformation • Multi layered air core inductor design • Spiral inductor design Electrocal is a collection of electronics circuit design tools, many engineers , hobbyist will find the tools very useful.
