A doorbell is connected to a transformer whose primary contains 3000 turns and which is connected to 120 VAC. If the doorbell requires 0.2 A at 10 V, find the number of turns necessary for the secondary winding and the current that flows in the primary.
Derive an expression for the optimum value of the avalanche gain opt M for which the signalto-noise ratio (SNR) becomes optimum by using the following expression for the excess noise factor: Fa( M)=KM+ (1-K ) (2-1/M). Assume that M^3 >> M .
a) A delta-connected three-phase source has a phase voltage of 220 V. It feeds a delta-connected load consisting of three identical impedances of 10/42° O each. Find the magnitude of the phase current in the load, the line current
If you have an M/M/Infinity system with arrival rate lambda and service rate mu(µ), how would you show that the expected number of packets in the queue is equal
The diode shown in Figure P8.36 has a piecewise linear characteristic that passes through the points (-10 V, -5 µA), (0, 0), (0.5 V, 5 mA), and (1 V, 50 mA). Determine the piecewise linear model, and, using that model, solve for i and v
A balanced three-phase load is connected to a balanced three-phase supply via a transmission line. What must be the readings on the two wattmeters, the ammeter, and the voltmeter
Products will be sold for $50 each throughout the life of the project and cash operating expenses will be $60,000 per year for years 2 through 7. Construct a cash flow diagram for the project.
If the transformer is connected to a load with 0.6 power factor leading, calculate the input impedance
A DC shunt motor connected to a 120-v line runs at a speed of 1200 rpm when the armature current is 18A. The armature resistance is .1 ohms. Assuming constant field flux, what is the speed when the armature is 50A?(Hint : Speed is directly porport..
Design a suitable amplifier using a combination of these stages. Your design should utilize the minimum number of stages and should ensure that the signal level is not reduced below 10 mV at any point in the amplifier chain.
Given one has frequency response of a system (magnitude and phase), and a sine wave of a given frequency and phase is input, explain how to find the output.
Assume that the machine is excited with a stator voltage amplitude that is directly proportional to the excitation frequency so that V1 = 13 pu. Consider three excitation frequencies we =13 = 1.0, 0.5, and 0.1 pu. Determine the maximum torque Tmax, t..
Given these parameters what is the resonant frequency and how did you get this value?
