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.
a 49pf cap,a 50 uH inductor, and a 100 ohms resister are in parallel: what is the resonance freq? And what is the complex impedance vector at 100MHZ?
When sizing wire, one of the most difficult tasks is to calculate the electrical load that will be present on the conductors. How do you decide what size wire to use? What two fact
Q. Briefly explain about Wye-delta transformation? Certain network configurations cannot be reduced or simplified by series-parallel combinations alone. In some such cases wye-
Q. (a) Consider a diode circuit with RC load as shown in Figure. With the switch closed at t = 0 and with the initial condition at t = 0 that vC = 0, obtain the functional forms of

PRINCIPLE OF LED
Boost Converter The boost converter has its output voltage always greater than input voltage like a buck converter boost converter has two modes.
UJT as a relaxation oscillator The UJT is a highly efficient switch it is used as trigger a device for SCR. No sinusoidal oscillators saw tooth generators phase contro
