Check what you remember
Read the wording for your board, then hide it and explain Potential divider ratio in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
For two resistors R₁ and R₂ in series across a supply of p.d. V_in, the p.d. across R₂ is V_out = V_in × R₂/(R₁ + R₂).
