Nordy Parrallel/Series/Single question

FWIW:

don't know what answer you're hoping but an appropriate response would have been more likely if you had alluded to as much.

Conceptually the simplest way that comes to mind is:

Series is like connecting two hoses to make one longer hose. In series current must flow through both coils to complete the circuit so that if a winding in one coil breaks neither coil will have output.

Parallel is like there are two hoses running side by side. In parallel current flows through each coil seperately so if the winding breaks in one coil the other will still have output.

Single coil is like there are two hoses but only one is being used. The other coil is excluded from the circuit and has no output.
