Why AC rated in Tons, Not in kW or kVA? (With a Guide about Airconditioner and Refrigeration)
A 4 pole DC generator has an armature winding containing a total of 648 conductors connected in 2 electrical parallel paths. If the flux per pole is 0.321 x 10^6 Maxwells and the speed of rotation is 1800 rpm.
Measurments taken of a square-wave signal using a frequency-selective voltmeter(called a spectrum analyzer) show its spectrum to contain adjacent components(spectral lines) at 98KHz and 126 KHz of amplitudes 63 mV and 49 mV
Design a synchronous sequential circuit with one input line and one output line that recognizes the input string x = 1111. The circuit is also required to recognize overlapping sequence such that if the input string is x = 1101111111010
An inverting amplifier is built using an opamp that has a 2V internal offset voltage. (You may consider the opamp ideal otherwise). The circuit uses a feed-back resistor of 2K and an input resistor of 1K. If a 2V input is given to the amplifier
Calculate the Fourier Transform of f(t) = 5 sinc(-2t/100), and graph the magnitude and phase as a function of f.If the signal of problem 1 is delayed by 0.1 ms. What is the new Fourier Transform. Graph it's magnitude and phase as a function of f.
If the motor is driving a load whose torque requirement remains constant at 3Nm, independent of speed. Calculate the armature voltage Va to be applied in steady state, if the load to be driven at 1500RPM.
Let a crappy voice channel occupy 1kHz. To ensure no interefence between channels due to nonideal bandpass filters add a 3.0kHz spacing between channels. How many simultaneous voice channels can you have if allocated a 87MHz bandwidth total
Calculate the percentage of electricity generation by these fuel-cell systems compared to the annual electricity generation in the U.S. of 3.8x109 MW-hrs
Fuel Cell produces current by using H2. Anode reaction: H2-->2H+ + 2e- Cathode reaction: 4e- + 4H+ +O2 --> 2H2O. The rate at which Hydrogen enter the fuel cell is given as 5 L/min. The temperature is constant at 300K.
A balanced three-phase load consists of delta-connected impedances in parallel with solidly grounded y-connected impedances. Express the currents Ia, Ib, and Ic flowing in the lines from the supply source toward the load in terms of the source..
A controlled three-phase six-pulse AC/DC converter is supplied with 60 Hz voltage of the line-to-ground RMS value U = 240 V with the output current ideally filtered by an inductor. The maximum DC power of the converter (Pd)max = 50 kW.
Design a 3-tap FIR lowpass filter with a cutoff frequency of 1,500 Hz and a sampling rate of 8,000 Hz using a. rectangular window function b. Hamming window function.
