Using Wolfram Alpha for Electric Circuits

For who doesn't know Wolfram Alpha is a computational knowledge engine: it generates output by doing computations from its own internal knowledge base, instead of searching the web and returning links.

Let's start with the basics :

Resistors

- calculate the color code for a resistor (example : 10000 ohm resistor)

- compute resistance from resistor color code (example : resistor black red red silver)

- compute resistance for resistors in parallel (example : parallel resistors 10k ohm, 2k ohm)

- compute resistance for resistors in series (example : parallel resistors 10k ohm, 2k ohm)

the last one is kinda easy :P you should know it too

Capacitors

- compute capacitance for capacitors in series (example : series capacitance 12uF, 6uF)

- compute capacitance for capacitors in parallel (example : series capacitance 12uF, 6uF)

- compute stored energy of a capacitor (example : capacitor energy 120mF, 2C)

- compute capacitive reactance (example : capacitive reactance 10uF, 50Hz)

Inductors

- compute inductive reactance (example : inductive reactance 25mH, 2kHz)

- compute self-inductance of a circular coil (example : inductance of a coil)

Diodes

- compute properties of a diode (example : diode 1.2 V or diode 120 mA)

It even can calculate more advanced things like :

Filters

- example : Butterworth filter or Chebyshev filter

Circuits

- compute properties of a circuit (example : 12A 24V)

-use input fields to specify data for an Ohm's law computation (example : Ohm's law)

- compute resonance frequency of an LC circuit (example : resonance frequency 12uF, 5H)

- analyze an RLC circuit (example : RLC circuit 20ohm, 6H, 300uF)

- compute characteristics of an AC signal (example : AC source 220V)

- examine op amp circuit configurations (example : op amp)

Also there are other areas where Wolfram Alpha shines, be sure to see the examples page. Stay sharp!
