Mam in our school they r using both leclanche cell instead of Daniel cell.... Nothing will happen mam..??? Plz reply mam... Tommorow I'm having my practical..😣😣😩😩
Actually we keep value of current constant during experiment but it’s not used anywhere in calculation so no need to connect. But if you want to connect you can connect in series with battery eliminator. Both way it’s correct whether u connect ammeter or not. I tried to simplify it for students.
The value of rheostat is 15 ohms 2.5 amp will work good and don't use any power supply unit as driving battery. Use a 6volt dry cell. Suggested buy a lecturer and trained in Physics practicals.
U have to supply voltage, it may be supplied by using either by using battery eliminator or by using battery as driver cell . Always emf of driver cell should be greater than emfs of other two cells for which u have to compare emfs of two cells.
@@rashmisblecturerphysics1580 I know that very well but use of A. C operated power supply/ battery eleminators will never give steady null point due to A. C. Ripple present at their output stage.
Battery eliminator convert Alternating current into Direct current so easily we can get null deflection point . Definitely we can use auxiliary battery which is having greater emf than the emfs of two cells for which we will compare emfs . . 6V is very high value.
Tommorow is my Physics practical exam
Very well explained
Thank you so much mam ✨
Awesome 🇮🇳🔥
To compare the emfs of two given primary cells using a potentiometer
Thank you .
Me Also watching this today coz of exam 😂
Thanks mam .. so helpful❤
me watching 1 night before my final exam
Wish u all the best
Same :(((
Same😅
Luckily I got this as recommendations🥺🥺❤️ Thank u so much ma'am 🙌🏻 Amazing explanation ❣️
Tnqs mam i searching all experiments this is best for me
Thanks a lot Mam 🙏🙏🌺
This video really helped me a lot .
Thank you dear ❤️❤️
🙏🙏
Amazing explanation.
Privileged to have such an amazing like you.
Thank you Ansh . May God bless you
Superb explanation Maam👍
Thankyou so much mam..best explaination ever.😀
Thank you for appreciation
Thanku so much ma'am ...this vedio helped me a lot 😇
Thank you Zeba for appreciating the video. ❤️❤️
@@rashmisblecturerphysics1580 most wlcm ....😇ma'am
Most helpful video. Thankyou
Thank you 😇
TQ mam😊😊
Wonderful explanation ❤️❤️❤️
Thank you Piyush
Resistance box is necessary
No not required
Mam in our school they r using both leclanche cell instead of Daniel cell....
Nothing will happen mam..???
Plz reply mam... Tommorow I'm having my practical..😣😣😩😩
Sorry for replying late. In case if both lechlanche cells are used ratio of E1/E2 will be 1:1.
Balancing leghth in both cases will be same .
Just now I have seen ur message 😔
@@rashmisblecturerphysics1580 it's ok mam...
Today's practical was superb...
Thanks u mam.. for the video...😊😊😃😃
Thank you dear ❤️
@@rashmisblecturerphysics1580 You are a really dedicated teacher mam😊😊😊😊😊...Really happy to find u in RUclips...😄😄😄
Love u mam❤️
Ty ma'am
Good
Thank you dear ❤️
Mam aapne ammeter to connect kiya hi nhi

Mam physics ke pratical toh smjh hi ni arey khi bhi🙄😭
Oh mam are u frm rudrapur🙄
Ty mam
❤️🌺
first learn. How to hold the camera
I’m performing experiment in this video someone else made this video for students benefit. Thank you for the suggestion. I’ll try to improve 😊
