A central air conditioner in a typical American home operates on a 220-V circuit and draws about 15 A of current.a. Determine the power rating of such an air conditioner.b. Determine the energy consumed (in kW*hr) if operated for 8 hours per day.c. Determine the monthly cost (31 days) if the utility company charges 13 cents per kW*hr.
What is the energy in joules stored in the capacitor below, The capacitor is shown with 10 volts on each side of it (plus on the left of the capacitor, - on the right), and C = 20 microfarads.
Design a circuit with input p and output f that will output f = 1 if the past three inputs (not including the current input), formed either 010 or 000. Otherwise, f = 0. Note: This is a Moore-type finite-state machine.
For the signal x(t) = 4cos(800p t +p / 4) + 8cos(1200p t -p / 3) - 4cos(1600p t) : (a) Sketch the double--sided spectrum of the signal, indicating the magnitude and phase of each component. (b) What is the period of x(t)
A constant current source of 2 mA is placed across a fully discharged capacitor of 100 F. In the time period before the capacitor reaches breakdown voltage, what is the time rate of change of voltage across the capacitor in V/s
consider the back to back cascade of an ideal C to D and D to C converter. Both have the same sampling rate fs. Suppose that the signal being sampled is: x(t) = cos(324*pi*t - pi/4) + cos(80*pi*t - pi/4)
A 5.00 cm thick layer of oil is sandwiched between 1.00 cm thick sheet of glass and a 2.00 cm thick sheet of polystyrene plastic. How long (in nano-seconds) does it take for light incident perpendicular to the glass to pass through this 8.00 cm th..
Design a 3rd order Butterworth High-Pass filter with a Fc of 2kHz and a passband gain of 2. Find the gain and critical frequencies of each individual stage. Plot the gain portion of the bode plot.
A sinusoidal signal is riding on a 2 v DC offset (in other words, the average value of the total signal is 2 v). Design a circuit to remove the DC offset and amplify the sinusoidal signal (without phase reversal) by a factor of 100.
3. For a simulated inductor application, to yield L = 75mH, R1 = 3kohm, and C1 = 200uF, determine required value of R2 4. For a constant current generator, with a saturation voltage = 20V and a current reference of 30mA, calculate RLmin.
a resistor is required for an application that requires its value to be no less than 7.1k ohms and not more than 7.9k ohms. determine the nominal value and the maximum tolerance of the resistor you could use. explain.
A critical aspect of web design is the approach that you take to define and develop the parameters of your site. This includes your review and assessment of your own work to validate your site to make sure that it meets the needs of your client.
A transformer on no load takes 4.5 A at a power factor of 0.25 lagging when connected to a 120V, 60Hz supply, the number of turns of the primary winding is 250. Calculate the magnetizing current, core losses and the maximum value of flux in the co..
