The formula will calculate the nearest 1%-resistor for the value in cell A1. This formula can be copied and replicated to other cells just like any standard Excel cell formula.

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 ...

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.

Like any tool, you have to understand what it is doing – 133,231 ohms may be the perfect setting for your circuit, but it is meaningless in reality, as your 100k resistor in that set is +/-1000 ...

Calculating the appropriate resistor values for a photocoupler isn’t complicated, but some basic min/max considerations must be acknowledged in when doing the analysis.
