Example to determine Dots
ECE 201 Circuit Theory 1
1
Assume current into terminal 1 and indicate with a dot
ECE 201 Circuit Theory 1
2
A Counter-Clockwise flux will be induced in the structure
Φ

3
We need to assume a current into one of the other
terminals to produce flux in the same (CCW) direction
Φ

4
Current into terminal 4 will
produce flux in the same (CCW)
direction
Dots on terminals 1 and 4

5
Note that terminals 2 and 3 could also receive a “dot”
Flux is now CW
