A power station supplies power at 11 kV, 0·8 p.f. lagging to a consumer through a single phase transmission line having total resistance (both go and return) of 0.15 Ω. The voltage drop in the line is 15%.
If the same power is to be supplied to the same consumer by two wire d.c. system by a new line having a total resistance of 0·05 Ω and if the allowable voltage drop is 25%, calculate the d.c. supply voltage.
Discuss the sequence of actions that occur in the operation of the control system for a traffic light that includes sensors in the roadbed. Indicate which actions are time-driven and which actions are event-driven.
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
A circuit has a Thevenin equivalent circuit consisting of a voltage source of 10 V and an output resistance of 20 O. A non-ideal voltmeter is used to measure the source voltage. What will be the measured voltage if the voltmeter has an input resis..
The program will store these values into an array and call a function that will return the average of the temperatures. It will also call a function that will return the highest temperature and a function that will return the lowest temperature.
A water tank, 22 ft in diameter, is made from steel plates that are ½ in. thick. Find the maximum height to which the tank may be filled if the circumferential stress is limited to 6000 psi. The specific weight of water is 62.4 lb/ft.
what is the impedance of a resistor r in parallel with a series combination of a capacitor c and an inductor l?
Design methodology (show calculations and provide rationale for design choices; remember that your choices must take into consideration commonly available parts). Final schematic in Multisim Components/Parts list Simulation results for your design Te..
The transfer function of a circuit is given by H(s)= 2s+4/4s^2+2s+2 a. Express the transfer function in a form in which the coefficients of the highest power of s are unity in both numerator and denominator.
What are the impedances of an inductor and a capacitor (of any value) at a frequency of 0 Hz (DC) and at infinite frequency. Once we know what they are , how can this information help us in analyzing a circuit.
A 200 foot transmission line that has a loss of 6db per 100ft has 100 watts inserted from a transmitter at 4 MHz . How much power will actually be at the antenna feed point.
Two infinitely long coaxial cylindrical surfaces, r = a and r= b (b > a), carry surface charge densities ρsa and ρsb,respectively. (a) Determine the electric field intensity everywhere.
An SSB generator has a 9 MHz carrier and is used to pass voice frequencies in the 300- to 3300-Hz range. The lower sideband is selected. What is the approximate center frequency of the filter needed to pass the lower sideband.
