This papercraft resistor calculator is the latest in the family of Circuit Playground tools that include a fabulous electronic reference app we reviewed some months ago.

Using standard resistor values can greatly impact the accuracy and predictability of a circuit by eliminating rounding errors incurred at the end of the design. Selecting resistor values traditionally ...

If you perform analog-circuit design, you'll occasionally need to use a resistor with a nonstandard value to produce a particular gain, ratio, or attenuation factor. You can create resistors of ...

To calculate the resistance of the series resistor required, we need to look at the current and voltage values recommended by the LED manufacturer.

There you have it – an LED resistor value calculator can help streamline your LED circuit design projects and free up your time, in more ways than you might initially imagine.

In the fields of engineering and electrical design as they exist today, the term “calculator” can refer to physical handheld calculators, as well as software tools. As of the 2020s, highly ...

Pi network attenuator circuit. SpinningSpark (CC BY-SA 3.0). A Pi network attenuator is a simple three-resistor circuit, as shown in the diagram to the right.

To calculate resistor values, we need to use Kirchhoff's Law: The sum of currents into a node is zero. Considering the node at the junction of the three resistors, we can write: ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, current and resistance in these circuits.
