如何使用 UliEngineering 在 Python 中根据电压和功率计算电阻值

English Deutsch Français 简体中文

你可以使用 UliEngineering Python 库，在已知电压和功耗的情况下轻松计算所需的电阻值：

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

# 计算 5V、1W 时的电阻
resistor = resistor_value_by_voltage_and_power("5V", "1W")
print(f"Resistor for 5V at 1W: {format_value(resistor, 'Ω')}")

# 计算 12V、0.5W 时的电阻
resistor = resistor_value_by_voltage_and_power("12V", "0.5W")
print(f"Resistor for 12V at 0.5W: {format_value(resistor, 'Ω')}")

示例输出

resistor_value_by_voltage_and_power_output.txt
Resistor for 5V at 1W: 25.0 Ω
Resistor for 12V at 0.5W: 288 Ω

电阻值使用以下公式计算：$R = \frac{V^2}{P}$
