Jab circuit open hai awr tho voltmeter voltage ki reading kaisay deta hai ????? Please sir reply

[@hassankhan1615]

thanks a lot sir ❤❤

[@factsbynaveedarif7367]

Sir jab circuit open hai tho po emf kaisay create hoa hai as emf is work done in moving a unit positive charge from low potential to high. Sir jab circuit open hai tho charge kaisay flow karta hai?????? Please reply

[@Saad-b4q4q]

Charge external circuit ma flow nhi krta Cell k andr krta ha bcz cell k both sides pe to potential difference ha q k ham na wires to lgai ha na bus farak ya ha k current aga flow ni krta

Sir Positive charges Vacant space nai hoti??tw Space kysy move kar k nagative ko utilize kary ga bulky Negative charges Vacant spaces ko fill karain gy....

Am i right sir?aren't?

[@afnankhan7992]

Toh conventional current phir kisy kehty hain! Isi ko toh kehty hain.

[@Bwonette]

​@eduacademy9584 no, positive charge means positive ions

Explain case of charging

[@IsmailKhan-wl9fw]

Mashallah😍😍

[@usernamestd-tn6zo]

Salam Sir I understand the topic But I didn't understand the case when charging then how emf is less then potential difference....

[@engrhilalofficial3231]

Sir EMF is work done per unit charge inside the battery,But when the circuit is open it means the charges inside the battery is not moving.. It means their is no work than why we discuss EMF in the battery...?? Waiting for answer please sir Thank you

[@mammonG786]

Why we have null vector or why point has no dimensions but all the points form a line ? Such questions can not be answered to a person like engrhilalofficial3231. It is like you ask about angeles that how many angels can sit on the tip of a sewing needle etc...........the scope of your question is research work which is as if you ask why 2+2=4 in school level where as it is to be asked in BSc. So my dear why are you trying to damage the brain of student at this level. Let the students of this level remain understanding what this level demands. 😂😂😂 mr engrhilalofficial3231 you can be a philosopher but can not be a teacher so start attending Philosophy classes instead of eating grass so openly.😅🎉😂 do say sorry to sir Atif on asking irrelevant question.

[@engrhilalofficial3231]

@@mammonG786this question is not in mind But It was frovm the side of my students dear 😅😅 By the way Question is not irrelevant If @Sir Atif Highlights at for us.. Thank you ❤️

[@eshacutie3448]

Good question

[@eshacutie3448]

Even though no current is flowing in an open circuit, we still discuss EMF because it represents the potential difference or voltage across the battery. It's like the "push" that the battery provides to the charges when the circuit is closed. So, even though no work is being done, EMF is still an important concept to understand in circuits. Hope that clarifies it for you!

sir we neglect internal resistance in emf thats why it having high voltage difference then potential difference plz answer someone

sir electrostatic me to potential difference ka def change ta ore yaha change plz sir make a vedio on this before exam

Sir ap charging wla case hi nhi btaya 😭😭😭😭😭😭 I was waiting for it....usko bta diya explain nhi kiya ....

[@MDCAT7604]

Why call donot show internal resistance in open circuit ?

[@Bwonette]

Because no current is flowing through it

First Comment Sir!

sir g ap Kay poray notes Milty ha ka

[@UmerFarooq-hg2ll]

sir ap ne closed circuit keliye EMF kese bataya wo to sirf open ke liye hota hai??

[@gbugraphicologycorner]

Actually emf sirf open ke liye hi nhi hota . It is also for closed circuit but humein e.m.f ki max potential value open circuit mein multi to I guess sir said it is only for open circuit because my sir got us write down three conditions for e.m.f. ○open circuit ○closed circuit (jis mein e.mf ziada hota potential difference se) ○when a a small battery is being charged by a bigger one (charging) jis mein e.m.f voltage se kam hota

[@gbugraphicologycorner]

Hope it helps. I did my best to explain even I am also having somehow confusion for it but I will go with the explanation my sir gave 😅
