1:11 - Step up autotransformer (Boost)
2:23 - Turns ratio (N1:N2) for step-up autotransformer
4:31 - Primary (IL) vs secondary (IH) current for step-up autotransformer
5:24 - Step up autotransformer current relationships and KCL
7:01 - Step down autotransformer (Buck)
7:26 - Turns ratio (N1:N2) for step down autotransformer
9:19 - Step down autotransformer current relationships and KCL
11:19 - Common current (IC) for both step up and step down autotransformer
12:30 - Input-output power formulas (SIO)
16:15 - Winding power formulas (Sw)
20:58 - Transformer turns ratio formula
23:16 - Set up autotransformer turns ratio formula
26:03 - Set down autotransformer turns ratio formula
Watch out!
The NCEES® Reference Handbook does not include reference material for the step-down autotransformer.
Instead, it only includes material for the step-up autotransformer.
Are you confident that you'll be able to answer step-down autotransformer questions on the PE exam without formulas or a circuit diagram?
This is a short video taken from the February 2022 Transformers Live Class to show you exactly how to solve step-down autotransformer problems, even though the Reference Handbook does not include any information on it.

I'm taking my test in a week, we'll see how it goes, but I want to say thank you for this excellent videos and for being such an excellent teacher. I'll make sure to recommend your videos to everybody.
Thanks for the kind words Daniel. Go get 'em next week!
I know this thing but still it is always good to refresh the knowledge and your video is the best of all to refresh the memory
Glad you enjoyed it!
GREAT JOB
