Limitations:
1. Silicon transistors do not function at voltages much higher than about 1,000 volts (SiC devices can be worked as high as 3,000 volts). In difference, electron tubes have been developed which can be operated at tens of thousands of volts.
2. High power, high frequency operation, like which employed in over-the-air television broadcasting, is better acquired in electron tubes because of enhanced electron mobility in a vacuum.
3. Silicon transistors are more vulnerable than as compared to electron tubes to an electromagnetic pulse produced by a high-altitude nuclear explosion.
For large number of measurements the mean is calculated by taking a sample. Each sample that is taken has a mean. The mean of various sample difference from sample and are known to
Q. In the non inverting summing amplifier of Figure, let R d = 1k and M = 6. Find R f so that v =
charges of +2q and -4q are fixed a distance d apart as in figure_2(a).find electric field at the point A ,B and C (b) sketch roughly the electric field lines.
What is reading mechanism of a 3 phase meter?
Q. Write a short note on the frequency response of a R-C coupled amplifier. At low frequencies ( , the reactance of coupling capacitor Cc is quite high and hence very small pa
Each year the University computer society holds a „virtual fair? in Second Life in order to raise money for charity. The main attraction at the event is a lucky dip, where attendee
