The first one is=-2
The second has the same polarity, and it has a rise of potential
For the third, it has the same polarity and it has a rise of potential.
that's correct?
According to the Kirchoff's law of voltages:
RT=6 ohms
VT=?
-2+3-2I+5-4I=0
6+-6I=0
6I=6
I=6/6=1A
is the result right? I have some doubts in the signs of the voltages.
I know that the sum of the currents in the circuit must be equal to zero and that the algebraic sum of the voltages must be equal to zero, I know this because I am self studying this topic, bue I don't have idea of the procedure to follow.

Another question, this method only applies in cases similar to this one, cases in which the probability is less than one? In a case when I already have the probability equal to one, do I only need to evaluate the function in the intervale (a,b) or I have to do another procedure?
