for the first question I planned to calculate the current immediately after by I=emf/total R. (1)I’m not sure why In the solution it says that no current reaches R2 and that it short circuits so we only use R1. (2)Also in general if had a circuit with two branches and one branch had an open switch would current not flow at all in the whole circuit or only flow in the branch with no open switch?
