Consider the half-wave rectifier shown in Figure. The ac source has an rms value of 20 V and a frequency of 60 Hz. The diodes are ideal, and the capacitance is very large, so the ripple voltage Vr is very small. The load is a 100-Ω resistance. Determine the peak inverse voltage across the diode and the charge that passes through the diode per cycle.
It is often convenient in the analysis of AC circuits to convert the series R-C or R-L branch to an equivalent parallel branch and vice versa as shown in Fig. 1 (a) and (b).
in a given byte-addressable computer, memory location 10000Hto 9FFFFH are avaliable for user programs. the first location is 10000H and the last location is 9FFFFH. calculate the following: the total number of bytes available (in decimal)
Experiment by changing the amplitudes of the modulating tones, and by adding a third tone to the modulating signal. First establish what you expect , then confirm by computer simulation.
There are two power system and susenergy problem. Include your email in your answer document.
Consider the two-pole two-phase induction motor having two windings displaced 90° in space shown in Figure.The fields produced by the windings are given by Ba = Kia(t) cos(θ ) and Bb = Kib(t) cos( θ-90°). The two-phase source produces currents giv..
The current in a solenoid is 5amps when it is connected to a 24v battery and 1.2amps when it is connected to a 24v, 60 Hz alternating current power source. Find the resistance and the inductance of the coil.
What would the effect of boundaries be on the diffusivity of a substance (e.g., if you have diffusion of a substance in a pipe, what would the effect of the pipe's walls be on the diffusivity
a. Is this a synchronous or an induction motor? b. Estimate the frequency of the applied armature voltage in hertz.
a single phase transformer has the following ratings: 10kVA,240/2400V. In the open circuit test with rated primary voltage(240V), the primary current is 0.85A and secondary voltage is2400V. A short circuit test is performed as follows
What is the magnetic force on a square loop of current I placed in a uniformed magnetic field B with the plane of the loop perpendicular to the magnetic field. Explain
a parallel plate transmission line is made up of perfect conductors of width w = .2m and d = .01m. The medium between the plates is a diaelectric of epsilon = 2.25*(epsilon not) and mu = mu not. For a uniform plane wave propagating down the line
Show that the time displacement in a periodic function has no effect on the magnitude spectrum, but changes the phase spectrum by an amount of -nω0τ radians for the component of the frequency nω0 if the time displacement is τ.
