Dimension of Pressure
Which of the following is a derived quantity
Luminious Intensity
Mass
Weight
Electric Current
Absolute zero on kelivin scale is equal to_______________
0K
-273K
-373K
100 K
In Charles law which of the following is constant
Pressure
Temperature
Volume
All of above
Absolute Zero temperature in degree celcius is________________
0ºC
273ºC
100ºC
-273ºC
In P-type Semi-conductor,Doping increases number of_________________
Electrons
Holes
Both notes and electrons
The electrical prperties of material depends upon number of elctrons in______________________
Innermost orbit
Outermost Orbit
Both of above
None of above
Who are minority change Carriers is N-type semi-conductors
Temp scales dgree celsius (ºC) and Kelvin are related by
ºC - 273 = K
ºC = K / 273
ºC = K + 273
ºC + 273 = K
100ºC will be when converted into kelvin will become
273 K
373 K
212 K
-273 K
