Saaari length hmae left side se hi leni hai?

[@AllLabExperiments]

@@ffeditz_ yes... But we change resistance boxes so that left side ka resistance neglect kr sake...

[@HemantYadav-ql1xf]

Hi...how to prove taking equal resistance P & Q will make senstivity of bridge maximum

[@AllLabExperiments]

@@HemantYadav-ql1xf jss drive the sensitivity and differentiate and put it equal to zero. In any book explaining carey foster bridge you may find the expression.

[@richakilawat]

Your explaination is just awesome sir👍👍
Sir may i know, why sensitivity of cary foster bridge in maximum when we take resitance P and Q equal.....

[@AllLabExperiments]

Sensitivity depends upon the voltage drop per unit length of the bridge wire. More length to drop 1 volt more the sensitivity. Acc to balanced wheat stone bridge expression use any combination of diff P n Q but you will get lesser value of sensitivity whereas this value is the max when P n Q are equal.

Thank you Sir.. It's a very good demonstration. Sir, if I will use two different P and Q value of resistance, then what will happen?

[@AllLabExperiments]

The formula will become a little bit complicated nothing else but also a high variation may shift your stable point out of range.

Yes, this is the way. You are right.

To determine an unknown low resistance using carey roster's bridge ka pdf digiye

Description me link h. Website pr file milegi

[@gaganarora3894]

For calculating the value of resistance per unit lenght of bridge wire, the value of resistance of P and Q should be same? Or they may be different?
Pls reply....

[@AllLabExperiments]

It is not mandatory but the sensitivity of the apparatus is the maximum in this condition and the calculation also becomes easy. that is why we choose equal resistances.

[@shubhra9974]

What is the value of X in part one and Y in part 2

[@AllLabExperiments]

Any small resistance like 0.1 ohm or so. Check the table given in this experiment.

[@feelknowledge3385]

plz tell on which software you made these presentation.

[@ffeditz_]

Saaari length hmae left side se hi leni hai? It doesn't depend upon the side of P and Q??????????

Yes one side. P and Q ki functioning ko switch krke you can use it for another side as well...

Sir ,why we use metal strip at ends when we measure specific resistance?...pls reply sir

It means there is no resistance. Rest I have explained the reason in this video or its viva voce video . The formula for specific resistance is drived with this condition only

[@bijoydas6044]

Namste sir🙏 , could you please give the approximate value of the resistivity of the carey foster bridge wire

[@AllLabExperiments]

It depends upon mny factors the thickness or the purity of the wire. The system i used had 0.02 ohm pr cm of resistance

🙂👍

[@shyamaprosadkar5083]

How to get the mean value ?

[@rikge]

It shows one side deflection only

[@AllLabExperiments]

No both sides. But you wan null point.

[@rupamkoch4901]

What is the function of P and Q resistance box

[@AllLabExperiments]

They are just to balance the setup. As their value increases the overall potential drop in the bridge wire decreases and the resolution of your setup increases.... Check its viva questions there in a flow the concept has been explained which is easy to digest...

[@salmasiddiqi9264]

What we will connect as low resistance in second part...could it be a copper wire ?

[@AllLabExperiments]

Its a copper strip.

[@salmasiddiqi9264]

In 1st part we are using copper strip..but what is using in second part in place of low resistance?

[@AllLabExperiments]

@@salmasiddiqi9264 that is a fractional resistance box. A box of very small resistances... Even less than 1 ohm

Sir what is the low resistance y just reply quickly hence tomorrow is my practical exam

A few ohms

[@feveathim184]

Why thick copper strip is zero? For carey foster bridge.

[@AllLabExperiments]

Its resistance is comparatively zero. Constantn wire carries some resistance.

[@feveathim184]

@@AllLabExperiments thank you sir

[@sriharithakancharla5443]

why cant we use an AC source??

[@AllLabExperiments]

Just you will get oscillating galvanometer at unbalanced points... So DC is preferred coz we dont wanna make life more difficult...

[@sairoopagaliveeti1198]

Why should we measure the radius of wire used in this experiment?(using screw gauge)

[@AllLabExperiments]

That is only required if you wanna calculate its resistivity. but as long as you want its resistance per unit length, you don't need to calculate its radius.
