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) How far is the spring stretched at the equilibrium postion B) How much potential energy is stored in the spring C) the mass is pulled down a distance of 4.50 cm and released. How fast is the mass moving when it is 2.50 cm above the equilibrium p..
A car with a projected frontal area of 1.8 m^2 is traveling at 136 KPH. If the drag coefficient of the car is 0.45 and the air density is 1.23 kg/m^3, find the total aerodynamic drag force on the car, and the power required to overcome this drag f..
Describe how you would use the voltage follower so the output load voltage (as measured with a scope probe) agrees with the value shown on the function generator front panel independent of load impedance. Describe any compromises or inefficiencies..
The two-wire 120-V supply line from the electric power company to the consumer has a resistance of 0.03 ohm. If a short circuit occurs at the consumer's residence, find the current that flows through the short-circuit.
A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 H. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0 when a 75 ohm resistor
Use Microsoft Excel to compare costs from at least three different vendors and reasons to accept specific bids. (May use graphs in Excel to provide a better visual comparison)
Find the sample space for the following experiment: Drawing bolts from a lot of 20, containing one defective D, until D is drawn, one at a time and assuming sampling without replacement, that is, bolts drawn are not returned to the lot.
An autotransformer with a total of 600 turns has its secondary winding embracing 200 turns. The 600 turns are connectred to a 60Hz, 2400V driving voltage. A load connected to the secondary draws 4.8kVA at 0.6 power factor lagging.
Several of the voltages associated with certain circuit are given by V12 = 9 phase angle 30 degrees V, V32 = 3 angle 130 degrees V, and V14 - 2 angle 10 degrees V. Determine V21, V13,, V34 and V24
A battery's lifetime was obtained as the time for the output to drop to 0.9 volt. The mean lifetime of these 152 batteries was 46.7 hours and the standard deviation was 13.3 hours. The industry standard for lifetime of such batteries is 45 hours.
Explain how to use the knowledge of Structure-Property-Processing-Perfomance relationship to improve on a device based on semiconductivity. Name the device, describe how it is made, the principle guiding its function and application.
A CB amplifier is operating with R load = 10 kiloohms, Rc = 10 kiloohms, and R signal = 100 ohms. At what current Ic should the transistor be biased for the input resistance Rin to equal that of the signal source
