How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The energy of a lightning energy model: This is an illustrative comparison value, not a claim that every example is the same.
Energy is an amount; power describes the rate of energy transfer or use.
