Meet the problem
We’ll use examples to teach a small program to estimate resistor losses. The rules it learns make up our model. This approach is called machine learning, one part of AI.
We’ll use DC current and a fixed resistance of 0.20 Ω. The equation gives us a reference answer, so we can see exactly where the model gets things right or wrong.
- Input
- The information you give the model. Here, it is current in amperes.
- Output
- The answer the model returns. Here, it is an estimate of power loss in watts.
P = I² × R
Power (W) = current² (A²) × resistance (Ω)
An ideal resistor: constant resistance, no temperature change. These are calculated examples, not measurements.
