a velocity sensor in attached to rotating the wheel. Design a circuit to provided a positive voltage whose magnitude is equal to the acceleration (revolutions pre minute) of the wheel. Assume the velocity sensor's output 1 mV/rpm, and the wheel rotates at less than 3500rpm.
Steel surfaces can be hardened by carburization. During one such treatment at 1000°C, there is a drop in carbon concentration from 5 to 4 at% carbon between 1 and 2 mm from the surface of the steel. Estimate the flux of carbon atoms into the steel
Design a NMOS resistive load inverter for: VDD = 5V P = 0.2 mW when Vlow = 0.1V kn = 60 micro Ampere / V^2 VTN = 0.25V Find the load resistor and the W/L ratio for the switching transistor.
Unpolarized light is incident on three polarizers: The first making an angle of 0 degrees with the vertical; the second making an angle of degrees with the vertical; and the last one making an angle of 90 degrees with the vertical.
1) Plot the impedance with respect fo frequency from 1Hz to 10MHz 2) Capacitor must be less than .1 of a 480 ohm resistor to be a good bypass capacitor for that resistor. What range of frequencies can we use this capacitor for
A 22KVA, 2300/230 VAC, 60HZ transformer is tested with a short circuit test. The measured data are as follows: Psc=280W, Vsc=80VAC and Isc=9.5 A 1. Find the transformer turns ratio of the transformer
The following test data were taken on a 110-KVA, 4400/440- volt, 60-Hz transformer: Short Circuit Test: P= 2000w, I = 200 amp, V = 18v Open Circuit Test: P=1200w, I= 2 amp, V = 4400v Calculate the voltage regulation of this transformer when it suppli..
A military satellite uses 10 GHz for the downlink frequency. The distance to the satellite is approximately 36000 km. if the satellite transmitter produces a power of 50 dBm with a transmit antenna gain of 20 dB and on the ground
A manufacturing plant has a 600V, 60Hz supply and the following loads: Lights: 24kW Electric furnace: 4.8 + j6.4 with a current of 150A Motor loads, 160kW at 0.8 Power Factor, lagging. What is the real power, reactive power, and aparent power
Gold cost about $100 an ounce in 1971. In 2007, the cost of an ounce of gold is hovering around $800. compute the average price increase for gold.
1) Compute the average power dissipated through the resistor 2) compute RMS voltage across the resistor 3) compute V RMS^2/R. 4) prove that P avr=V RMS62/R for any periodic voltage waveform
Shielding Effectiveness with copper and steel at equality, Determine the frequency at which two 1 mm thick shields, one made of copper and the other of steel
