Sir Apke sarre practicals worth to watch the Mere college mein abhi practicals hoe or I almost watched all of your videos Jazakallah ke apne practicals kese cheez KO itna Acha smjhya Jo koi nhai smjhata❤❤❤

Salam...sir voltage or resistance k drmiyan inversely proportionality arahi hay....ye to ohms law kay bar aks hay...confuse hogaya hu ..reply me soon...nehrbani hogi

Mashallah piyara ❤️

Sir calculated resistance value 2933 ohms Arhi and Resistance 100 200 300 400 krke li hai means 100 ka gap h .....toh yeh theek hoga yaa wrong?

[@karamnarejo2799]

Voltmeter parallel circuit mei lagta hai ya series mei?

[@SasukeUchiha-qe3ik]

voltmeter series mei lag hi nahi saqta! Yeh pata nhi konsi duniya mei hai.

[@khan_affan]

Since we have find internal resistance of voltmeter... We are connecting voltmeter as a resistive component... And as there are two resistances (one resistance box and other voltmeter) thats why voltage is divided in these two components...

Sir mine practical went good because of yuhhhhh ☺☺☺☺☺☺☺❤❤ You are a life saver 😌 May Allah give you success Ameennn

sir can you tell me imp practicals for 2023?

[@AlexAtis-ut6zn]

How to calculate the extensions

[@toobasiddiqui3533]

What is the use of sand paper in this?

[@khan_affan]

Wire ke ends ko saaf karnay k liye... It is recommended k saaf karkay circuit lagayein jayein... But normally connected miltay hain...

Sir these are Sindh board practicals?

[@khan_affan]

Yes

[@ayesha24237]

Sir ,,,,to determine coefficient of linear expansion of material of given rod by pulling apparatus ye experiment bhi upload krdein

[@khan_affan]

I am so sorry, not possible now ...

Sir circuit diagram practical main perform krni hogi ya sirf samjhne ke liye hai

Salam sir......Can u tell k important experiments knse hai bcoz hamare clg m 4 experiments nhi krwayen hain only 9 r done

[@khan_affan]

Walaikum Salam... Jo college me karwayein hain sirf wohi ayengy... Do check your Journal in practicals k elawa bhi or hosaktay hain...

Sir tu yeh value 3065 calculated value of resistance of a voltmeter hogi....aur graphical value of resistance of a voltmeter 2700 hogi jo apnay find out ki h graph k through..?

[@khan_affan]

Yes blkul...

[@maryamrafiq3415]

Sir standard value kia he or answer kitni range me askta he?

[@khan_affan]

Ye voltmeter pe jahan 3V or 15V likha hai, yahan likha hota hai internal resistance kitna hai iska... To aap uspe dekh saktay ho apnay college me, normally 3V wala 3000 Ohm hota hai baqi college ke apparatus pe depend karta hai...

[@eishahilal3215]

sir aik baat confirm kardien hum apnay resistance ki value apni marzi say rakhien gay like jitnay bhi digits 100s ya 1000s kay gap say rakhna chaien ....or hum voltage ki value resistance kay mutabiq nikalien gay ju humnay khud se lekhi thien

[@khan_affan]

Normally voltmeter k resistance ki value 3k and 12k Ohm hoti hain jo hum log market me aam tor se dekhtay hain... Or normally hum 3k wali value pe lagatay hain (agar ghor se voltmeter ko dekhein to uspe likha hota hai)... Ab raha aap ka sawal, to normally 3k tak pohanchnay k liye humein 5-6 readings banani hoti hain to isi liye behtar hai k 500 Ohm har baar apply karein takay 6 readings tak 3000 tak pohanch jayein...

Sir percentage error bata dain urgent

[@khan_affan]

Aap ka jo bhi answer araha houn usme se standard (actual) value minus karein or standard value se hi divide kardein... And multiply by hundred to convert it into percentage... E.g. Water ki actual Specific Heat 1 Cal/g°C hai... Agar aap ka answer 0.9 araha hai... Ab aap 1 me se 0.9 minus karein or 1 se hi divide kardein... It will be 0.1, phir 100 se multiply karein the answer will be 10... Iska matlab 10% ka error hai... Hope its clear...
