1. Do we still use this rule at AS or is this a GCSE rule or something? Does it still hold true?
2. what do you mean, I've ever heard of that?

I assume you mean in terms of current. yes and no, it is a viable argument in an explain question but you have to use calculations. Also you learn about resistors in series and parallel. There will be a higher current through the resistor with the lower resistance, if the pd (voltage) across the resistor is the same. V=IR V-voltage I- current R-resistance.

I see. Thank you!
