Thanks Sir. Sir I have practicals in two days can i emember sin theta value. sir also what is weight of pan used in video

super

Sir can we take further readings by moving the needle pin instead of convex lens?

Book jo vedio me use kiye ho uska naam bta do plz

Par key kha he😂

Thanku sir..❤

On the way for practicals

Thank you so much sir ❤

best video ever thankyou sir

Aaj kis kis ka practical hai😂

Jitna yad rakho practical experiment viva to nahi ane bala exma me , kuch experiment bi nahi hoga shirf phir bhi external marks 28/30 to 30/30

Timestamps 00:05 - Learn to determine resistivity using potential vs. current graphs. 00:45 - Resistance is caused by collisions between electrons and atoms. 02:07 - Calculating resistivity requires resistance, length, and area of the wire. 02:51 - Measuring voltage and current to determine resistivity of materials. 04:24 - Measuring voltage and current to determine wire resistivity. 05:10 - Connecting wires and components to complete the experiment circuit. 06:49 - Minimum measurable voltage and zero error in the experiment. 07:39 - Observations for measuring wire resistivity using an ammeter and voltmeter. 09:01 - Setting up voltmeter and measuring current during resistivity experiment. 09:40 - Setting up voltage and measuring current in a resistivity experiment. 11:18 - Calculating resistivity using given current and resistance values. 12:15 - Calculating the radius using a screw gauge in resistance experiments. 13:59 - Understanding zero error in measurements for wire resistivity. 14:39 - Determining wire diameter using measurement scales. 16:06 - Calculating resistance values for wire resistivity experiment. 17:13 - Calculating resistivity from resistance measurements involves performing multiple trials. 18:51 - Understanding the experiment setup for measuring wire resistivity. 19:32 - Experiment demonstrates resistivity measurement using Ohm's law.

Thank u very much sir ❤

Graphhh???

Thank you sir 🙏

Bhai ye practical me kya kya karna hota hai. ...like ..experiment or question answer suunana😢😢please. Tell❤

Thank you Sir Very Helpful Video sir

Sir plan surface me,circular scale ka "0" main scale ka line ke sath match karna jaroori hai ya koi bhi reading ho sakta hai,suppose agar error ho to? Error me to circular ka 0 match nhi karega, usse thoda upar ya niche aa sakta hai(plain surface me)?? Kya spherometer me error find out karna hota hai like vernier calipers or screw gauge?

sir key kyu nhi lagaya aapne ?

Thank you so much sir May God always bless you sir 🙏🙏

Sir it is asked for 2 or 3 wires so game practical main 1 ke ka hi karna Hain kya ? And graph BHI banana hain

Bahiya iska pdf mil sakta hai kya

50 min before exam

Worth to watch this video

Great explanation

Great explanation

Thank u very much sir ❤ But in my class mA is used ?

This video is very fascinating sir

Real practical from 4:37

Watching 1 day before practical 😅

❤❤❤

😮

Thank you sir 🙏

Helpful

So you are the best teacher I think so I have ever seen in my life it's help me a lot in board examination practical

thank you sir

Rough focal lenth kese calculate kare bata dijiye please 🙏 🙏 🙏 🙏 🙏

After 30 min my practical is there THANK YOU🎉

Thank you so much sir!!

1 second bad practice hai 💀💀💀💀☠️☠️☠️

Sir reading 0 se shuru ni karenge aapne 0 ke upar se ki hai

Sir aapne bahot achhe se kaam time me samgha diya ❤ Thanks 😊

👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻😻

Vry well explained sir..👍🏻👏🏻

Sir may practical shik gaya

Key connect nhi h sir....bina key connect kiye reading shi aaata h kya sir??

Ye jindagi ke kis kone me kaam aayega bagwaan jane 😅😊😂

Today is my practica,l thank you so much

Helpful ❤

Graf nahi samJh me nahi AAYA
