A coil of 20Ω and inductance of 212mH is connectedin parallel with a 106μF capacitor. The circuit is connectedover a 180V, 50Hz(variable frequency source) supply.1.) Calculate the total Current drawn from the supply .2.)Calculate the value of the frequency where the circuit willbehave as a pure resistor.3.)Calculate the value of impedance at resonance.4.)Calculate the Q-factor for the circuit at resonance.
a)Write the diffrenece equation for a four-term moving average filter. b) The input x[n] = cos(n pi/6)u[n] is passed through the four-term moving average filter. Solve for the first 5 samples of the output.
Given a voltage of 100 volts with a phase angle of 0 degrees, applied across an impedance of 50 ohms at an angle of +30 degrees. This is an inductive impedance - not TOTALLY inductive, but more inductive than capacitive.
A 480-V, 60Hz, 500-hp 0.85-PF-leading eight-pole delta-connected synchronous motor has a synchronous reactance of 0.6 ohms and neglible armature resistance. Ignore its friction, windage and core losses for the purposes of this problem.
What is the basic of AC circuits What is the way to understand Impedance and application of the laws of Kirchoff, Nodal, Ohm etc on AC Circuits
1.The Thyristor is a natural commutation device. What does that mean. 2.Mention two reasons why the HVDC might be your choice as a power system designer to transfer large amount of power.
y[n]=x[n]+0.8x[n-5000]+0.6x[n-8000] a) Find the delay in seconds for each echo if the sampling rate is Fs=10000 Samp/sec. Td1 and Td2 a) Find the unit sample response for the filter written as the sum of delayed unit-samples.
lets suppose there are two capacitors of same capacitance and they are connected separately to there own battries now we joined both the capacitors togathers and are connectd to the battery with wires of the same potential
The dielectric constant of LiF is 9.27 at low frequencies and approaches 1.9 at high frequencies. What are the percentage contributions of electronic and ionic polarization to the low-frequency polarization
A variant of the binary symmetric communication channel described in class is called a binary erasure channel. The transmitter sends a ‘0' or ‘1,' but at the receiver there are three possibilities: a ‘0' or ‘1' or ‘undecided bit..
The four alkaline battery cells store a total of 200watt-seconds of energy. If the cassette player is drawing a constant 10mA from the battery pack, how long will the cassette operate at normal power
Construct an inverting Dc integrator circuit using a jumperwire to act as the switch across the feedback capacitor. Notice that the input voltage is 0 V, so the output voltage shouldnot change, even after the switch is opened.
A trough is 8 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x^{8} from x=-1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty
