Check what you remember
Read the wording for your board, then hide it and explain Relationship between current and resistance in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Because the potential difference across each branch is the same as the power supply, the total current leaving the supply increases, so according to R = V / I the total resistance must decrease.
