Design a half-wave rectifier power supply tto deliver an average voltage of 9V with a peak to peak ripple of 2V to a load. The average load current is 100mA. Assume that ideal diodes and 60Hz. ac voltage sources of any amplitudes needed are available. Draw the circuit diagram for your design. Specify the values of the compnents used.
The cutoff frequencies of a series resonant circuit are 5400 Hz and 6000 Hz. a. Find the bandwidth of the circuit. b. If Qs is 9.5, find the resonant frequency of the circuit.
An hydro-electric station has a turbine of efficiency 86% and a generator of efficiency 92%. The effecitive head of water is 150 m. Calculate the volume of water used when delivering a load of 40 MWfor 6 hours. Water weighs /000 kglm3.
Given the 16-bit operand 00110101 11001010, what operation must be performed and what operand must be used a) to clear all odd bit positions to 0 (Assume bit positions are15 through 0 from left to right.)
We represent this by a non-overlapping sequence detector. In other words, asa soon as you detect the sequence, you will need to get another complete sequence to unlock. Therefore, you need to carefully choose to which state you will need to go.
A coil of 2000 turns surrounds a flux of 5 mWb produced by permanent magnet. The magnet is suddenly withdrawn causing the flux inside the coil to drop uniformly to 2 mWb in 1/10 of a second. What is the voltage induced.
The work function of platinum is 4.09ev what retarding potential will be required to reduce the photocurrent to zero in a photoelectric experiment with Pt electrodes if the wavelength of the incident light is 2440 angstrom
The neutralization occurs on-line in the discharge piping by addition of acid or base as required based on upstream pH measurement. draw an appropriate control scheme using the simplified ISA symbols.
Consider the thermal noise produced by a resistor. How does the noise level change if the resistance is increased by a factor of 100 Next, assume the noise is passed through an ideal, noiseless low-pass filter.
Document your test plan in a table. For each test case, document the expected program behavior and the actual program behavior. If the program does not behave according to your prediction, write a brief explanation of what the program did wrong.
Design a zener shunt regulator to provide an output voltage ofapproximately 10V. The supply is a 20V± 20% source andthe load current varies from 0 to 20mA. The zener availablefor use is a 1 watt zener with Vz=10.2V at Iz=20mA and rz=10Ω.
A constant torque of 5Nm is applied to an unloaded motor at rest attime t = 0. The motor reaches a speed of 1800rpm in 4s. Assumingthe damping to be negligible, calculate the motor inertia.
why sinusoidal wave is chosen for AC fundamentals rather than a simple curve such as square or triangular wave?
