Energy Efficiency
Often used for batteries, heating systems, and fuel.
η = Eout / Ein
- Eout: Useful Energy (J)
- Ein: Total Energy Input (J)
Efficiency
Efficiency - Perform scientific calculations with precision and accuracy.
Efficiency
Efficiency quantifies useful output relative to input, often expressed as a percentage.
Formula
η = (output / input) × 100%
Example
80 W output from 100 W input → η = 80%.
FAQs
Thermal vs electrical?
Define inputs/outputs consistently for domain.
Losses?
Consider heat, friction, and parasitics.
