Design a full wave (Bridge) rectifier as a dc power supply that provides a peak dc output voltage of 15V on which maxiumum of 5% ripple is allowed. The rectifier feeds a load of 200Ω. The rectifier is fed from the line voltage (120V rms, 60 Hz) through a transformer. The diodes have 0.7 VA) Draw the full wave (bridge) rectifier circuit to design. Include the line voltage and the transformer.B) Determine N1:N2 turn ratio.C) Find the required value of the filter capacitor.D) Find the maximum reverse voltage that will appear across the diode.
The length of GaAs laser resonator is L = 165 um; the width and the thickness are W = 10 um and d = 0.1 um. Find the photon round-trip time in this resonator. The refractive index of GaAs is 3.7.
A sequential circuit with two D flip-flops, A and B; two inputs x and y; one output z; is specified by the following next-state and output equations: A(t 1) = x' y x A B(t 1) = x' B x A Z = B a) Draw a logic diagram of the circuit.
What is the maximum symbol rate that the twisted pair line can carry without ISI? 256-QAM modulation is used on the link. How many bits are conveyed by each symbol?
how do you determine the value of Xl in a parallel resonant circuit, when all youre given is Xc, Rcoil, and the parallel resistance
A 6 pole, 60 hz induction motor is wye connected and has a rated slip of .03 with the follwoing parameters: Rs=0.5 ohms, Rr'=0.3ohms, Xs=J1 ohms, Xr'=J0.35 ohms, Xm=j20 ohmsand the total rotational losses=7300 watts.
A heat pump maintains a dwelling at 68 F. When operating steadily, the power input to the heat pump is 5 hp, and the heat pump receives energy by heat transfer from 55 F well water at a rate of 500 Btu/min.
When electros and holes are present in a semi-conductor, the presence of an electric field produced by an external voltage will cause this carries,which have changes of oposite sign, to move in opposite directions.
