It provides fast, accurate solutions for essential circuit calculations and component design—streamlining filter design, amplifier analysis, component sizing, and more. Whether you work with resistors, capacitors, inductors, transistors, or op-amps, Electrocalc delivers the tools you need.

Key features:
• Series & parallel resistor and capacitor calculators
• Inductor design tools (toroidal, spiral, air-core, multilayer)
• Transistor CE load line analysis with plotting
• Series & parallel RLC circuit calculators
• Reactance & resonant frequency computations
• Resistor and capacitor code converters (SMD, ceramic, polyester film)
• PCB trace width calculator and transformer design utility
• Decibel calculator and dBm-to-watt converter
• RF utilities: skin-depth, impedance, and waveguide calculators
• 555-timer astable & monostable configuration tools
• Operational amplifier calculators (non-inverting, inverting, differential)
• Network tools: voltage divider, current divider, Wheatstone bridge calculators
• Filter design calculators: RC, RL, band-pass, band-reject, Butterworth, Chebyshev, Bessel, and Sallen-Key
• Power regulation: Zener diode regulator, adjustable regulator, attenuator design (T, Pi, Bridge-T)

Electrocalc combines all these calculators into a single electronics toolkit that helps you save time, reduce errors, and master complex concepts. Its clean interface and clear outputs make even advanced RF design straightforward.

I like it a lot however..... What it needs to do is update the graphics based on the variables. For example resistors in parallel. As you increase the number of parallel resistors update the graphic to represent the same.

its a bit simple, can certainly use some work but overall useful if you know what you're doing. would be useful if there was a way to insert an output like you can the other variables. such as an input field for time with the 555 timer. id also suggest showing the equations that are being used so that one can understand what is happening and why.

if the scaling improves, the rating will too. very bad graphic experience. fields are off screen & cut off. otherwise it does the calculations as advertised
