Hello, I have the following question regarding autotransformers and dot convention (please see attached).

Can anyone give any guidance? I think I have an answer for part (a) but not completely sure if this is correct as I haven't come across a similar example before, sorry about the lack of subscripts on the numbers.

(a) V1 = jωLI1 + jωM(I2 + I1)

V2 = jωL2 (I2- I1) + jωMI1

If the above is correct I think I can do (b) and (c) but if it's incorrect then I would really appreciate some pointers.

Thanks
