- In this Physics video in Hindi for Class 12 we explained the structure and function of an AC Generator. We also derived the equation for the induced emf using faraday's law of electromagnetic induction. This topic is from Chapter 6 : 'Electromagnetic Induction' for Class 12 from NCERT.
AC Generator : It is an electrical device which converts mechanical energy to electrical energy. It generates alternating current. When a coil is rotated in a magnetic field, magnetic flux associated with the coil changes, due to which an induced emf is created. That induced emf generates electric current.
Principle - It is based on the principle of electromagnetic induction.
Construction - The AC generator consists of the following parts.
1. Field Magnet - It is a pair of strong concave permanent magnetic poles. In the figure they are represented by N and S.
2. Armature - It is a rectangular coil ABCD consists of a large number of turns of copper wire wound over a soft iron core.
3. Slip rings - The leads from the arms of the armature are connected to two rings separately. These are called slip rings.
4. Brushes - These are the flexible metallic pieces (B_1 and B_2 in the figure) which allow the current to pass from the slip rings to the external load R.
Working - When the armature is rotated in the magnetic field, the flux linked to the coil changes and hence, current is induced in the coil.

As a teacher I am also try to follow your way of teaching
🙏
@@edupoint.physics I have a doubt that why magnetic field is circular and it is usually 1 Dimensional unlike Electric field which spread all over in 3 dimensions.but Magnetic field is usually defined under 1 dimensional.why this happen?why magnetic field is usually one dimensional??
Who think this is one of the underrated channel on TH-cam, because sir deserve more than it.
Thank you sir... Please continue the series with your Great explanation!🙏
Very good voice
Your teaching like unbelievable sir❤️👍
Behtareen sir
Your video very appreciative i watched all of your video for knowlege
one of the most underrated channnel
I am very big fan of your voice 🤩💖🤩
Sir i form nepal and i always used to watch your video while confusing while doing mcq since 2 year .Thank you sir 🙏❤️
Great👍👍
Great explanation
thanks for wonderful video
Sir I promise you i will be a good teacher like you.i am bsc first year student I am learning physics from you.thank you sir ji
A very nice explanation 👍
Sir, carbon brushes kis material se bane hote hai
Loved it.
Sir, in dynamo or ac generator emf is produced so it is better to use fleming's right hand thumb rule not the left one.
Because right hand thumb rule was specifically made to know the direction of induced emf just like lenz' law!
Rest of explanation was great!
Yeah that's handy !..but it's the derivative of the left hand rule only ..so he only tried to give us that insight !
Sir i am also an educator.....please bta dijiye ki aap pdhane ke liye ya likhne k liye konsi app use karte hai
I am also teaching 10th standard boys you are my inspiration sir, thanks 👍
APA ka voice bohat acha hai sir
sir phy ke aur videos bnaye pease
Cse lover
Edupoint is better than all ather platform
🙏
Ye to aapka pyaar hai, jisse aapko aisa lagta hai.
Thankyou so much sir ❤️
Samjhane ka tarika koi aap se sikhe, sir !
