In this class and next class I just explained simple circuit connection and verification of ohms law / finding resistance of wire fixed at the wooden plateform but for resistance per unit lenth you need to divide resistance calculated with 50 cm which is length of that wire. But if you want to understand how to find resistance per unit length then go to playlist 'Class12:ISC Physics practical ' and go through demonstration of 2019 question paper of electricity. ruclips.net/video/IafD4pku1AU/видео.html Three classes Reading of paper How to perform How to draw graph and write in exam copy (with calculation).
@@physics_pratibha it means we can use rheostat or resistance box. Mam your videos are amazing it will help me a lot in my ISC practicle exam which is on 30 Dec.
In Rheostat we can not find how much resistance is introduced in the circuit so we use resistance box as we are aware of the value of resistance introduced in the circuit .All the best child.
u r still helping us thanks mam
Mam this experiment is -To find resistance per unit length of a wire by meter bridge ?
Verification of ohms law
@@physics_pratibha mam is verification of ohm's law and finding resistance per unit length is same?

@@physics_pratibha ok mam
thank you so much
Thank you ma'am ❤❤❤
🙏🙏
Ma'am class was great 👍
so clear
Mam in 2023 what type of question can come?
Most of them are covered in playlist ISC class 12 physics practical
Mam experiment 5 kha pr hh 4 ke badh sidha 6 show horha h
Corrected playlist.find in playlist
Mam where we use rheostat
We use Rheostat or resistance box where we need to change resistance of circuit and that way control the current in the circuit
