Definition of Analogy between electrical and mechanical systems
Check what you remember
Read the wording for your board, then hide it and explain Analogy between electrical and mechanical systems in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Charge is treated as displacement and current as velocity, so the capacitor's voltage corresponds to the spring's restoring force.
