What is the Electric field of the TV broadcasting station? (Hint: Provide Electric field for any TV broadcasting station, but provide the reference)
If water is extracted from the lake at 15°C and 10 kg/s of steam at 0.0622 bars are to be condensed, what is the corresponding temperature of the water leaving the condenser? The specific heat of the water is 4180 J/kg · K.
a) Consider an n-p-n transistor whose base emitted drop is0.76 at a collector current of 10mA, What current will it conductat Vbe=0.70V. What is the base emitted voltage for ic=10microampere. b)A CE amplifier uses a BJT with B=100, Va=50V, biased a..
a. Describe the operation of a typical NMOSFET transistor used both as an amplifier and a switch. b. List the 3 regions of operation and draw the I-V characteristic curve. c. Show the effect of channel length modulation on your graph.
An amplitude modulated amplifier has a radio frequency output of 50w at 100% modulation. The internal loss in the modulator is low. What output power is required from the modulator.
An OP-07 operational amplifier has ca GBW of 0.5 MHz and a slew rate of 0.17 V/s. If the closed loop gain is set to 15:
Choose a product or technology that uses base band digital communi- cations and find out what line code it uses. You may not choose RS-232 serial links or similar, or Ethernet because we talked about their line codes in class.
Determine the capacitance as a function of Ri and Ro. If the dielectric is polystyrene of relative permittivity, εr = 2.6, calculate the capacitance of an isolated conducting sphere of a radius 0.4cm(i.e., Ri=0.4cm and Ro goes to infinity).
The electron and hole concentrations as a function of energy in the conduction band and valence band peak at a particular energy. Consider silicon and assume Ec - EF =0.20 eV. Determine the energy, relatiive to the band edges

A 460-V, three-phase,60-Hz system supplies power to a 10-kVA, delta-connected resistor load; a 50-kVA, 0.86 power factor induction motor, and a wye-connected synchronous motor that is operating at 0.62 power factor leading
Using a computer program in excel plot the electron concentration of silicon doped with 1×1013 cm-3 phosphorus as a function of temperature. Use a temperature range from 300K to 800K. Assume that Nc, Nv, and Eg are temperature-independent
A proportional controller for a rotating antenna has a gain Kp of 5 in-oz/deg. The antenna was initially pointing due south, but was then commanded to point southeast. Find the initial torque supplied to the antenna.
