Electrical power transmission
What Electrical power transmission means in Physics A-Level, as defined for AQA.
Definition of Electrical power transmission
Check what you remember
Read the wording for your board, then hide it and explain Electrical power transmission in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The transfer of electrical power through cables that have resistance, so some energy is dissipated as heat.
