Energy efficiency in power transmission
What Energy efficiency in power transmission means in Physics A-Level, as defined for AQA.
Definition of Energy efficiency in power transmission
Check what you remember
Read the wording for your board, then hide it and explain Energy efficiency in power transmission in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Zero-resistance cables would remove I²R heating losses, raising efficiency, though refrigeration still consumes energy.
