Homework Statement
Hi all
I have been struggling to find the right ans for the I(R1) in this circuit.
First i consider only the voltage source by opening the current source. As such i find that I'(R1) = (4-0.7)/1K = 3.3mA
Secondly i consider the current source by shorting the voltage source. Thus i derive I''(R1) = 3mA
Finally i get I(R1) = I'(R1) + I''(R1) = 3.3m + 3m = 6.3mA
However the ans seems to indicate as only 3.3mA.
Please help to see if my reasoning is correct.
Thanks.
