1. Describe briefly your concept of a scalar field and illustrate with an example.
2. Describe briefly your concept of a vector field and illustrate with an example.
3. How do you depict pictorially the gravitational field of the earth?
4. A sinusoidally time-varying vector is expressed in terms of its components along the x-, y-, and z-axes. What is the polarization of each of the components?
Find the transfer function, X3(s)/F(s), for each system shown:
Explain how optical solitons can be generated in an optical fibre. How could the same phenomena be used for pulse compression?
All Questions need to be answeredTASK 1: Understand common configurations for controlled and uncontrolled rectification
Calculate the efficiency of transmission at the IP level. Assume no options for the header and no errors. Calculate the efficiency of transmission at the data link layer. Assume no options for IP header and Ethernet-II format are used at the d..
If the current line voltage is 460 V, what must the generator's operators do to correct for the low terminal voltage?
An 8 pole, three phase 50kVA, 220V, Y connected synchronousgenerator has a synchronous reactance of 4.8ohms per phase andoperates in stand-alone. Neglect all loses. The field voltage isadjusted to give rated voltage across the output terminal at n..
Our third word problem case study described a logical "function unit" that computed the eight combinational functions of the inputs A and B: constant 1, A OR B, A NAND B, A XOR B, A XNOR B, A AND B, A NOR B, and constant 0.
What is the minimum value for each of the individual decoupling capacitors?
If the products are rounded as described in part (a), the output can be represented as yˆ[n] = y[n] + f [n] where y[n] is the output owing to x[n] acting alone, and f [n] is the total output due to all the noise sources acting independently. Deter..
a capacitor, an electric resistance heater, and an impedance are connected in parallel to a 120 volt, 60 Hz. system. the capacitor draws 50 VARs, the heater draws 100 watts and the impedance coils draws 269 VA at a power factor of 0.74 lagging.
Energy stored in a spherical capacitor. A spherical capacitor is formed by two concentric, conducting shells (Figure 4.77). What is the change in stored energy if the dielectric is removed? Assume a known charge +Q on the inner shell and -Q on the..
Based on emf and torque equation compare and contrast the two methods of speed control of dc motor.
