For the B) part, I don't get why is it that for calculating voltage between collector an the emitter (Vce) I take into account diode on base (0.7V), whereas for part A) it's ignored?
Why is Vce in part A and part B are calculated differently? Why is it that in part A voltage of 0.7V isn't taken...
Okay, so why is it that Vc assumed to be 12v - 0.7v (D1), how about contribution from the 9v battery?? Why is this not affecting the voltage at node C?
Why Vc isn't 9v - 0.7v (D2) = 8.3v?
Good evening people. Recently I started taking the "electric network analysis" course in my school. We already saw the mesh analysis method for solving circuits. Now we are seeing the node analysis method. I understand that the first step for this method is finding the number of nodes (and one...
Homework Statement
From the above circuit find VCB and VDG
Know Data:
VE = 0 (ground)
Homework Equations
KCL and Ohm's Law are used in Node Voltage Method.
The Attempt at a Solution
I decided I would determine the node voltages then work out VCB and VDG afterwards.
1. KCL and Ohm's law at...
