In electrical and electronic problems, you will often solve for the resultant of three
vectors. Two of the vectors will be on the Y axis; the third vector on the X axis. For
example, to combine the three vectors below, we first solve for the resultant of the two
vector on the Y axis.
The resultant vector on the Y axis is __________________- .
Next step..solve for the resultant of the vectors on the X and Y axes. When two vectors
are at right angles (see drawing below), you cannot add the two vectors algebraically;
they must be added vectorially.
