Hi,
The following are the questions along with explanations that are asked previously in ISRO recruitment for Scientist/Engineer post.
The following are the questions along with explanations that are asked previously in ISRO recruitment for Scientist/Engineer post.
- The temperature below which certain materials are antiferromagnetic and above which they are paramagnetic is called Neel Temperature.
Other Types of temperatures :
- Weiss temperature
- Curie temperature
- In metals, the thermal conductivity K and the electical conductivity sigma are related as K/(sigma*T)=L. L is known as Lorenz number
- The cavity magnetron uses strapping to preventing mode jumping
- The TWT is sometimes preffered to the magnetron as a radar transmitter output tube because it is Capable of a larger duty cycle
- One of the reason why conventional vaccum valve tubes not used at microwave frequencies is that their Noise increases.
