How to compute parallel resistor values in Python using UliEngineering

You can easily compute the total resistance of parallel resistors using the UliEngineering Python library:

parallel_resistors.py
from UliEngineering.Electronics.Resistors import *
from UliEngineering.EngineerIO import *

# Compute total resistance of two parallel resistors
total = parallel_resistors("1k", "2k")
print(f"Total resistance: {format_value(total, 'Ω')}")

# Compute total resistance of three parallel resistors
total = parallel_resistors("1k", "2k", "3k")
print(f"Total resistance: {format_value(total, 'Ω')}")

Example output

parallel_resistors_output.txt
Total resistance: 666.7 mΩ
Total resistance: 545.5 mΩ

The parallel_resistors() function accepts any number of resistor values as arguments and computes the total resistance using the parallel resistance formula:

$$R_{total} = \frac{1}{\frac{1}{R_1} + \frac{1}{R_2} + \dots + \frac{1}{R_n}}$$
