    12. sir in terms of sign convention near the nucleus the potential energy is minimum and kinetic energy is maximum right? so in that case the potential energy of an electron in a atom will be maximum at infinity?

    13. But why are the holes being influenced by the Electric field as they are not in C.B....if so.. then the electrons in V.B should also be influenced..right?

    14. how temperature affect conductivity of conductor
    10 years ago by abhishek agarwal
    Ans 1 ->
    on rising the temperature conductivity of conductor also increases and vice versa.
    9 years ago by ashok sahu
    Ans 2 ->
    rising temprature conductivity of metallic conductuctos decreases
    8 years ago by Nishit Goyal
    Ans 3 ->
    Rising temperarture decreases mobility of electrons ( due to more no. of collisions ) & thus decreases the conductivity .
    8 years ago by Ashish Sharma
    Ans 4 ->
    On increasing temperature conductivity of of a conductor decreases while we decreases the temperature conductivity of the conductor decreases.
    7 years ago by Devashish Choudhary
    Ans 5 ->
    On increasing temperature conductivity of the conductor decreases while we decreasing the temperature the conductivity of the conductor increases.
    7 years ago by Devashish Choudhary
    Ans 6 ->
    r=r o ( 1 alpha*dt) on increasing the temperature resistance increases and resistivity increases... resistivity is inversely proportional to conductivity
    6 years ago by ABHISHEK SHANKAR
    Ans 7 ->
    R= Ro ( 1 alpha * dt )
