如何使用 UliEngineering 在 Python 中计算分压器的功耗

English Deutsch Français 简体中文

你可以使用 UliEngineering Python 库轻松计算分压器的功耗：

voltage_divider_power.py
from UliEngineering.Electronics.VoltageDivider import *
from UliEngineering.EngineerIO import *

# 计算 5V 输入下 10k 和 10k 电阻的功耗
power = voltage_divider_power("5V", "10k", "10k")
print(f"Power in 10k+10k divider at 5V: {format_value(power, 'W')}")

# 计算 12V 输入下 1k 和 9k 电阻的功耗
power = voltage_divider_power("12V", "1k", "9k")
print(f"Power in 1k+9k divider at 12V: {format_value(power, 'W')}")

示例输出

voltage_divider_power_output.txt
Power in 10k+10k divider at 5V: 1.25 mW
Power in 1k+9k divider at 12V: 14.4 mW

功耗使用以下公式计算：$P = \frac{V_{in}^2}{R_{top} + R_{bottom}}$
