Question:
Using the following expression, derive expressions for the electric and magnetic field intensities in terms of components of A→, that are TEM to the z-direction (TEMz):
E→ = - jωA→-j .1/(ωμε).∇(∇.A→)
The single phase for equivalent circuit parameters for the windings of the motor referred to the stator in (ohms/phase) R1=0.2 R2=0.2 X1=0.3 X2=0.3 .the core losses and the magnetization can be ignored.
Design a regulated DC power supply for the following specifications and verify your design using SPICE. Design Restrictions: Capacitor values in your design should not exceed 50 mF. In case if you need a bigger capacitor use an op. amp. based capac..
A silicon diode has a doping profile such that ND = ax3. What is the depth of the junction assuming the p side is uniformly doped with NA per cubic cm. Assume the x origin is at an ideal ohmic contact on the n side of the diode.
A motor connected to a 220V(rms), 60Hz voltage source is marked as drawing a current of 13.5Amps(rms), with a power factorof 0.72 lagging and an efficiency of 83%. Suppose that the motor operates according to these specifications.
Important information about Frequency Divider, Design a frequency divider circuit that will output three pulse frequencies: 25 kHz, 10kHz, and 2.5kHz. Assume that only a 150 kHz CMOS compatible signal is available for the divider input
Compare the three rectifier ( half wave, full wave and bridge rectifier) to design a 20 V supply with 1V ripple for a 1Kiloohms load. In the comparison look for the filter capacitor, transformer turn ratio n and the PIV of the diodes.
A given application written in Java runs 15 seconds on a desktop processor. A new Java compiler is released that requires only 0.6 as many instructions as the old compiler. Unfortunately, it increases the CPI (clock cycles per instruction) by 1.1.
