Plz tell me, why stepdown operation occurs in full load condition
I need such a video in all the rules of magnetism
Great video! Thank you so much for taking the time to explain this so fluently. May I ask a question though, in regard to a step-up transformer, is it more important to use the same size wire as the primary? For example, I could wind the coil many more times with a very thin wire as opposed to the same gauge used in the primary wind. What if I was to use a really HUGE gauge wire? I might only get a hand full of winds, but the wire is thicker. I know big wire = big power, does this apply? Lastly, What about instead of one continuous wire, we use a thick gauge insulation but inside, there are many smaller wires. This wouldn't be a continuous loop, but many MANY wires would be wrapped around. What would the difference be between the secondary being looped with one single wire vs a large gauge conduit, with many wires inside of the same mass? Apologies if I am not asking the right way or if I am confusing you with my limited knowledge on the subject.

type of wire only affects resistance thick or thin they are effective
So what would the current be for power source before a resistance was added
While 240 V is well within the operating range of most Australian appliances, the nominal voltage throughout Australia has been 230 V since the '80s.

I stand corrected.
I have two transformers, If NS and NP of both have a ratio of 2:1, one transformer 20 turns and 10, then the another transformer 200 turns and 100 what is the advantages and disadvantages and character of each? Regards Great video btw

using math efficiency is same . in a the first flux leakage is higher than in the second even thouhg it is affected bychanging the design
As V=IR, if you increase voltage, current will increase as well with the similar factor. So how could the power remain conserved?

If the voltage is stepped up, the current on the load side will be determined by V=IR. However, if you then measure the current drawn on the source side it will be higher than the current on the load side, to be be consistent with Law of conservation of energy It may help looking at my video (start at 5:39) kzread.info/dash/bejne/aJ-Bzcahh83Te7w.html

High School Physics Explained You didn't get what I mean! In primary supply(source side), V=IR applies, giving voltage is directly proportional to current. But at 5:40 in this video you says (so does my school teacher) that Vp is inversely proportional to Ip. They are contrasting statements, how can they both be true?

V=IR applies to single circuits. Not wanting to go into a long winded explanation, this link might help www.blueraja.com/blog/194/do-transformers-obey-ohms-law

High School Physics Explained you just earned a subscriber! Thank you a lot to pay attention to my doubts. I appreciate and hope that you upload some more knowledgeable videos until October 30, 2017 (HSC).
for current it is sure if only efficiency is equal to 100%
