1. Discuss briefly the motional emf concept.
2. What is Lenz's law?
3. How would you orient a loop antenna in order to obtain maximum signal from an incident electromagnetic wave which has its magnetic field linearly polarized in the north-south direction?
4. State three applications of Faraday's law.
What is the logic function performed by the circuit? - Determine the transistor W/L ratios to provide symmetrical switching times equal to the basic CMOS inverter.
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
A full-wave silicon rectifier is used with a power transformer to generate the DC output voltage for a low current application. Assuming the storage capacitors are sufficient to eliminate power supply ripple
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120 V rms. The load draws a total of 10 kW at a power factor of 0.85. Calculate the rms value of the phase currents
Assume a maximally flat N = 5 response, and solve for the necessary line lengths and impedances if Z = 10 and Zh = 150 . Use CAD to plot the insertion loss versus frequency
Assume both antennas are ideal.
1) What is the difference between a continuous spectrum and a line spectrum 2) What is the fundamental difference between a continuous signal and a discrete signal 3) Why are linear time invariant (LTI) systems so important in engineering and enginee..
Will a 12VDC power supply capable of delivering 1 amp be able to power this heater (resistor). Use Ohm's law to show whether or not the power supply will be able to deliver the required current.
A wafer 100mm in diameter is mounted in an electron-beam evaporation system in which the spherical radius is 40cm. Use Eq. 6.7 to estimate the worst-case varation in film thickness between the center and edges
Find the imaginary part of e^ - (j pi)/2 Find the magnitude of e^ jtheta (for any real value of theta) Find the magnitude of Ae^( j theta) (for any real values of A and theta) Find the phase of -5j in radians
