Suppose the government cuts taxes. Using a supply and demand analysis of the capital market, explain what the impact of the tax cut will be on the equilibrium real interest rate at full employment.
What is the path attenuation between transmitter and receiver at a frequency of 1.2 GHz and a distance of 11,000. Given: f = 1.2GHz d = 11,000 mi. Calculate the path attenuation; dB = 37dB + 20 log f + 20 log d = 37 + 20 log 1.2^9 + 20 log 11,000
A device moves 120 coulombs of charge from point a to b in 8 seconds. the distance between a and b is 6 cm. the energy expended in moving the charge is 600 Ws. calculate the voltage between a and b.
A coil of resistance 50 Ω and inductance 0.318 H is connected in parallel with a circuit comprising a 75 Ω resistor in series with a 159 μF capacitor. The resulting circuit is connected to a 230 V, 50 Hz a.c. supply. Calculate:
A three-phase, 2300-V, 60-Hz, cylindrical-rotor synchronous motor has a synchronous reactance of 10 ohms per phase and negligible armature resistance. The motor delivers 250 hp at a power angle of 20 electrical degrees, and the efficiency is 90%
use MATLAB to compute state transition matrix and then obtain the step responses y1(t) and y2(t), given that the initial state vector is zero
Consider a Δ-connect, 25 kVA, 480 V, 60 Hz, six pole synchronous generator. The field current is set such that the line voltage is 504 V when supplying a rated load. Consider the armature resistance to be negligible.
Use Electronics Workbench to determine the current in each resistor of the circuit of Figure 6-21(a) if a 24-V voltage source is connected across the terminals of the resistor network.
A winding consists of 50 turns of a metallic conductor in a loop square with sides of 0.20 m in length each. The winding has center at the origin with two sides parallel to the axis of x the other two sides parallel to the y-axis
What is the RF bandwidth occupied by signal? What is the frequency range of the transmitted RF signal?
where Jn(β ) is the nth order Bessel function of the rst kind with argument β. Using Matlab, plot the magnitude spectrum of a single-tone FM signal |S(f)|.
Design a linear DC motor for propelling and braking a track-guided vehicle. The vehicle contains a generator to power the electromagnet with current Ic for the generation of the flux density B. The track region carries a current . Assume that the ..
A mealy sequential circuit has one input (x) and one output (z). z can be 1 when the fourth, eighth, twelfth, etc. inputs are present, and z=1 if and only if the most recent input combined with the preceding three inputs was not BCD encoding of a ..
