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.

Programs calculate 1% and ratio-resistor pairs Selecting the best resistor technology for the application Five questions about resistors Resistor Noise—reviewing basics, plus a Fun Quiz The hidden ...

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. Suppose a manufacturer recommends a maximum ...

How a Simple LED Resistor Calculator is Helping DIYers and Engineers Save Time March 22, 2025 by David Edwards Time will always . Tuesday, 02 January 2024 12:17 GMT.

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 ...

“Your impedances are set by resistor values, which are reliably available over a huge range.” The resistive pi pad is just a special case of the general pi network – with three impedances Z1 ...

Engineers connect components in electrical circuits in series or parallel to make a range of useful circuits. We can calculate the voltage, ... the current through each resistor is the same.

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: (V IN - V AD )/R1 ...
