Hi guys, Sorry if all you guys think this question is too easy. But I have a hard time to understand how to group the resistor. I suppose to find the the thevenin and Norton equivalent circuit. This is what i think about the combination of resistor. Req1= RL+1k Req2= Req1 ll 3.3k (3.3k after node a) Req3= Req2 + 3.3k (3.3k before node a) Req4= Req3 ll 5.6k Is my prediction correct?
