This lecturer is the best I have ever seen. I study at Australia doing electrical power 3rd year and they don't even thought us this

[@sandeepa2732]

Thank you sooooo much ma'am . Now i am your student..

[@prahladarora1875]

thank you so much... :) i owe my FE marks to you :)

[@jakerzsickle]

When a^2 (a squared) is used to bring secondary winding resistance/leakage inductance to the primary, i don't understand, does a^2 have a value? How would you work out R1/a^2? Thanks

[@Studyyaar]

for that you'd have to first understand impedance transformations for a short video refer here Transformer Impedance Transformations - Reflecting Impedances to Primary and Secondary or visit my website studyyaar dott com for full set of lessons. the link to lessons on transformers is given in video description("About" Tab)

[@vinothramesh3414]

please upload detailed problem about oc &sc tests

[@krishnamurthy1940]

Nicely explained
