A couple of days ago I attended an exam where I was asked to calculate
- Voltage at node A;
- Voltage at node B;
- Current provided by the voltage source.
Using node analysis I managed to find voltages at node A and B (I got 12.13 for VA and 5.84 for VB), but I am still having difficulties in finding the current provided by the voltage source (V1 in the circuit). How can I calculate the magnitude of this current?
