electronics.ohms_law.ohms_law(voltage: float, current: float, resistance: float) → dict[str, float]

Apply Ohm’s Law, on any two given electrical values, which can be voltage, current, and resistance, and then in a Python dict return name/value pair of the zero value.

>>> ohms_law(voltage=10, resistance=5, current=0)
{'current': 2.0}
>>> ohms_law(voltage=0, current=0, resistance=10)
Traceback (most recent call last):
  ...
ValueError: One and only one argument must be 0
>>> ohms_law(voltage=0, current=1, resistance=-2)
Traceback (most recent call last):
  ...
ValueError: Resistance cannot be negative
>>> ohms_law(resistance=0, voltage=-10, current=1)
{'resistance': -10.0}
>>> ohms_law(voltage=0, current=-1.5, resistance=2)
{'voltage': -3.0}
