| Rahul prajapati asks : thank you for your answer. But Sir,how bursting of tyre is adiabatic process?, please explain. sir i think that bursting of tyre is isochoric process as tyre tube has constant volume & in summer season tyre tube expands as temperature increases (since at constant volume pressure is directly propotional to temperature )due to more expansion tyre tube can't tolerate this pressure & burst out . Is i am wright sir? if it is wrong, then what is correct explanation for it. |

| Kshitij bathla asks : we say that resistance is opposition to current and so higher the resistance lower value of current will be thr and so output voltage v=ir must remains always constant but it never happens why????? |
Sir,
M a student of class 11..
I do say!!
All that let it deflect is that with resistance temperature of the wire do deflect and hence the eletricity
flowing do vary
coz of temperature deflection!!
