A single-phase transmission line supplies a reactive load at alagging power factor. The load draws 1.2 pu current at 0.6 puvoltage while drawing 0.5 pu (true) power. If the base volageis 20 kV and the base current is 160 A, calculate the power factor and the ohmic value of the resistance of the load.
A 20-KΩ / V voltmeter reads 10 V full scale. (a) What series resistance is required to make the meter read50 V full scale (b) What power will the series resistor dissipate when themeter reads full scale
The following measurement were made on a two-port resistive circuit. With port 1 open, V2 =15V, V1 = 10 V, and I2 = 30 A. With port 1 short-circuited, V2 = 10 V, I2 =4 A, and I1 = -5 A. Find the parameters of the z-parameter two-port.
When we discussed the work of Galvani and Volta, we noted that Galvani's work was not fully appreciated until the development of instruments capable of detecting and amplifying the small biopotentials present in living organisms.
A transmission line operating at 125 MHz has Zo = 40 Ω, α = 0.02 (Np/rn), and ß = 0.75 rad/m. Find the line parameters R', L', C', and G'.
Determine the energy or the power in the signal. x(t) = e-a*abs(t) where a > 0 and abs(t) means the absolute value of t.
Draw the logic diagram for the 4-bit circuit, using full adders and multiplexers. Determine the arithmetic operation performed for each of the four combinations of S and Cin: 00, 01, 10, and 11.
You are an electrican working on a industrial plant. A circuit contains eight incandescent lamp connected in series across 480v. one lamp has burned out and you must determine which one is defective. you have available a voltmeter, ammeter, and oh..
Design a 3-input CMOS OR-gate using MOSFETs on the CD4007 chip. Make certain that the power dissipation is zero when the output is both logic 1 and logic 0. As an added challenge, design the OR gate using the minimum number of CD4007 chips.
Determine the peak-to-peak current ripple in the output inductor for a forward converter and determine the output voltage ripple of the converter . We know the following parameters: duty cycle d, input voltage Vin, turn ratio: N1/N2
Shirlee is working with a measurement tool that reports measurements in centimeters. Since Shirlee is unfamiliar with centimeters, she would like her centimeter measurements to be converted into yards, feet, and inches.
What is correct symbol rate (pulse rate) for this link? What is the bit rate with BPSK modulation? What is the bit rate with QPSK modulation?
A BCD-to-seven-segment decoder is a combinational circuit thatconverts a decimal digit in BCD to an appropriate code for theselection of segments in a display indicator used for displayingthe decimal digit in a familiar form.
