Most of these questions probe pupils’ understanding of potential difference (or voltage) in parallel and series circuits. Qs1-4 all test understanding that the p.d. (voltage) across resistors connected in parallel to a battery is the same as that of the battery.
Qs 5-6 then test understanding that the current in a parallel branch is the same as it would be if this were the only branch present.
Qs 7-8 test understanding of branch currents, and current in the main circuit, when an extra parallel branch is added.
Qs9-10 deal with series circuits, testing understanding of how p.d. (voltage) behaves.
