@@FilterGross the formula for heating is I²RT. My doubt is if for example we increase resistance by 2 than because of V=IR, current will decrease by 2 times so the new heating will be (1/2)²2T =1/2T. So doubling resistance made the heating half.
Sir, today's class was very good , I enjoyed it...😊Sir bring more questions like...this.. so we can perform best in our boards... Thanks sir for this amazing questions series
27:56 sir can we use p=vi formula. I tried of using that formula because same question is in ncert i had done that also with this formula but in this question my answers 25 w is not coming
Sir galvanometer nhi dikhaya tha baki sab tha or ... There are 2 symbols for galvanometer: -Here the alphabet G signifies galvanometer. -Here the arrow mark signifies the needle present in the galvanometer. There is no specific positive or negative side to it. So galvanometer bhi answer ho skta hai
17:26 guys one thing to do it in 1 second That as you know for series v is directly proportional to r and 13ohm resistance will get more volt than 12 ohm so
dear students all the best all of you score 95+💝
Ab toh lgta 95 % ayiye ke manega😂 , joh video nikalo udhre .....dear students I wish you get 95 %😂🤣😂😂
Thanx

18:42 assertion is correct but reason is not correct explanation of assertion 💯💯💯💯💯

47:29 assertion is wrong but reason is correct 💯💯💯
Sir nichrome doesn't have High resistance, it has high Resitivity. Any material can have high resistance.
jiska rho high hota hai unka r bhi high hota hai
direct relation hota hai
1:03:30 i didnt understand. shouldnt less resistance mean more current meaning even more heating? then why is the statement wrong??
Bruh no, the higher the resistance the higher is the heating. Because it stops the smooth flow of current.

V is directly proportional to i in ohm's law but in p=vi ..p/v=i here i is inversely proportional..why is it so?

1:06:23 sir answer 2 ampere hoga kyuki battery ka internal resistance 1 ohm each hoga
Yes

27:56 sir can we use p=vi formula. I tried of using that formula because same question is in ncert i had done that also with this formula but in this question my answers 25 w is not coming
Same I have also done like that and 50 answer is coming
Because r is constant

Sir u deserve more subs and likes😢❤
Thank you sir muja ye hi chaiye tha ❤❤❤
12:36
Yaha pe resistance hlf hona chaiye rha
Answer b is correct
Bhai question Change bhi to ho skta hai zruri thodi hai whi hoga
Questions are fantastic❤❤
Sir is ques m temperature change hua h toh phir isme toh ohms law applied hei nhii hoga 1:01:24
Pls repy sir 1:01:25
Sir you are great 👍👍👍👍👍👍👍👍👍
Sir , option c hoga }, because resistance increase ---- current decrease ------ potential difference will also decreased I= VR
V= I R

Sir questions are very intresting
39:22 sir but ammeter positive should be connected to positive terminal and negative of ammeter should be connected to negative terminal
To vaise hi to laga hai
I was also thinking about that.

Galvanometer tab hoga jb option me Rheostat nahi hoga Google pr yahi same question maina search Kiya to uska answer "rheostat" hi bta rha hai
