Structure and Working Principle of Transformer || AC - 10 || in Hindi for Class 12

In this Physics video in Hindi for Class 12 we explained the structure and working of a transformer. We derived the equation for the input voltage and the output voltage. This topic is from Chapter 7 : 'Alternating Current' for Class 12 from NCERT.
Transformer is an electrical device which changes the voltage of an ac source. Its working is based upon faraday's law of electromagnetic induction. It has an input coil known as the primary coil and an output coil known as the secondary coil. The ratio of the input voltage to the output voltage is same as the ratio of the number of turns in the primary coil to that of the secondary coil. That means the voltage in coils is directly proportional to the number of turns in the coil. Whereas, current in the coil is inversely proportional to the number of turns in the coil.

Sir you are god of physics please make more videos

[@bali425]

Sir saare chapters ke videos pure pure daala kijiye, koi koi chapter mein kuchh chapters missing hai...❤

[@SIGMA_SHORTS_CLUB]

Big fan sir

[@tuntunyadav11]

Thanks sir

[@farmanbeg9199]

Sir please ab is chapter ke bad wave mosition par bhi video bana do na sir please

[@abeshenam9967]

Sir plz make a video on line integral 🙏

[@villageera8801]

Sir please Bsc Physics ke bhi videos banaye

[@virag2987]

opeartional amplifer pe video banav

[@farmanbeg9199]

Mane wave motion ko edupoint class 9th par pada ab kuch 11th ka pad leta to 11th physics complete ho jati sir

[@Onlinebar005]

♥️♥️♥️♥️
