Useful online tools and calculators for electronics
1. Ohm's law
A very useful reference for converting one electrical quantity to another. I use it all the time - it helps a lot with calculations.
You can also use online calculators:
2. Online capacitance converter (pF-nF-µF)
The page also includes a table of numeric codes (CODE) printed on capacitor bodies and their corresponding capacitance values.
3. Resistance. Resistors
-
Online LED current-limiting resistor calculator.
-
Resistance calculator for parallel and series resistor networks.
-
Online resistor parameter calculator based on color coding (select colors from the list)
-
Online SMD resistor value lookup based on its printed code.
5. Online circuit simulators and design tools
-
EveryCircuit - circuit simulator tool
- Scheme It - circuit design tool
