The current flows from Vout. The resistors now are not considered. Switch open> Vout positive > then the Red diode should be forward, in order to light up.the current flows from the right vertical bar carrying three resistors in a row as switch is only connected to the left bar with two resistors ...track the path of the current ...when v = + ...and ull understand tht it will pass through the red LED..i didnt mean to say tht it is generated frm the ground .. i was talking abput the pathway
I am at least 95% sure
