Question

How to know the sign of the IR=dif.V in a resistor?

Luisa Real · Accepted Answer

If the direction of I(current) is the same in which you are transversing, the IR should be negative=drop in the IR.
If the direction of I(current) is the opposite in which you are transversing, the IR should be positive= rise in the IR.
