Isaac Physics 'A Power Problem', ProblemWatch
I was confused at first so looked at the hints and saw they'd split the circuit up into different parts labelled A, B and C. There was another post I saw made on this question, and for parts A, B and C they got values of 3Ω, 20Ω, and 6Ω respectively. When calculating them myself I got the correct values for A and B, however for C I could not see how they'd arrived at 6Ω. Could someone please just quickly explain this to me please?
