arrive at In? (Or do you?) Am I wrong thinking you arrive at In

using the first resistor closest to the output terminals (as with

Thevenin's Theorem)?

My DC instructor spends one class per theorem, obviously not too

little for other students; and obviously I'm never going to be an

electrical engineer. I have a B average and would like to get my

associate's in computer technology. (Plus I would dearly love to

understand material I have shelled out big bucks to assimilate.)

Anyway, if Rn=Thn, could someone tell me how you arrive at -48.2mA for

In in the following problem? The Rn here was given at 56.9. (The 33

resistor is depicted as being in series with the 3 Volt source; the

other two are depicted in parallel.)

Also, as long as we're on Norton's, and if anyone is so inclined,

could you help with In for the following?
