CONDUCTANCE
- Conductance:-
- Current flowing property in conductor are called conductance
- It is provide to easy path of current.
- The reciprocal of resistance are called conductance.
- S-I Unit of conductance is "mho or seeman".
- dimension of conductance is:-
- Conductivity/Specific Conductance :-
- Unit length and unit cross section area of conductor provide the easy path of current, this property is called Conductivity.
- Conductivity is just like a molecular conductance of substance.
- The reciprocal of resistivity are called conductivity.
- SI-Unit of Conductivity is "mho/meter" or"seeman/meter".
- Low of Conductance:-
- Dependency of Conductivity:-
- It is not depend on length of a conductor.
- It is not depend on cross section area of a conductor.
- It is depend on nature of substance or internal structure of a substance.
- It is depend on temperature.
- In conductor, conductivity is negative temperature coefficient.(NTC)
- In conductor, temperature will be increased than conductivity will be decrease (vice versa).
- In semi conductor, conductivity is positive temperature coefficient.(PTC )
- In semi conductor, temperature will be increased than Conductivity will be increase (vice versa).
- In insulator, conductivity is negative temperature coefficient.(NTC)
- In insulator, temperature will be increased than Conductivity will be decrease(vice versa).
- Dependency of Conductance:-
- It is depend on length of a conductor.
- If length will be increased than conductance will be decrease(vice versa)
- It is depend on cross section area of a conductor.
- If cross section area will be increased than conductance will be increased(vice versa)
- It is depend on nature of substance or internal structure of a substance.
- It is depend on temperature.
- In conductor, conductance is negative temperature coefficient.(NTC)
- In conductor, temperature will be increased than conductance will be decrease (vice versa).
- In semi conductor, conductance is positive temperature coefficient.(PTC )
- In semi conductor, temperature will be increased than conductance will be increase (vice versa).
- In insulator, conductance is negative temperature coefficient.(NTC)
- In insulator, temperature will be increased than conductance will be decrease (vice versa)
TEMPERATURE EFFECT OF CONDUCTIVITY IN SEMI CONDUCTOR
- Thermal expansion of Conductivity in Semi Conductor:-
- Thermal expansion of Conductivity in Semi Conductor present in "Linear Expansion".
- Linear Expansion of Conductivity :-
- Any Semi Conductor change of conductivity is directly proportional to the original conductivity as well as change of conductivity is directly proportional to the temperature difference.
- Rise in Temperature:- If conductivity at zero degree Celsius is given , Find the conductivity at T degree Celsius is:-
- Cooling in Temperature:- If conductivity at T degree Celsius is given , Find the conductivity at zero degree Celsius is:-
- Find the relation between thermal coefficient two different temperature in term of Conductivity:-
- Find the relation between Conductivity at two different temperature but Thermal coefficient given at zero degree Celsius :-
