Part ASimplify the circuit by replacing the lower Δ (25 ohm, r2 = 57.5 ohm and 40 ohm) with its equivalent Y as shown in (Figure) . Determine the resistances of the equivalent Y.
Express your answers using three significant figures separated by commas.
Part BDetermine the current supplied by the 40 V source in the circuit.
Express your answer to three significant figures and include the appropriate units.
Part CDetermine the magnitude of the power supplied by the 40 V source in the circuit.
The ADC requires a 10-V input voltage for full-scale binary output. If an amplifier is placed between the potentiometer and the ADC, what amplifier gain should be used to take advantage of the full range of the ADC?
a.) find the fourier coefficients of the exponential form b.) find the fourier coefficients of the combined trigonometric form c.) plot both the single sided and double sided amplitude and phase spectra
[1] If the speed of a DC machine is doubled and the flux remains constant, the generated e.m.f. (a) remains the same (b) is doubled
An RC circuit has a capacitance C=100μF. The voltage across the capacitor is vc= 141.42 sin1000t. Find the instantaneous expression for the current. If a voltmeter is connected across the capacitor and an ammeter in series in the circuit,
EENG 4319 - Power System Analysis and Design, Describe in 500 words the impact of power transmission line on society and Discuss in 300 words the ethics involved in such a project.
if the power factor of the motor be changed to 0.866 lagging. - Determine the reading of the two wattmeters, the total power remaining unchanged.
The function is to take in the values of increment inc and maximum interval value Imax and assuming the sweep interval begins at zero calculates imax, the required number of iterations using imax=ceil (Imax/inc+1).
Assuming there is no power constraint on the users, give an approximate expression for the achievable spectral efficiency (bits/s/Hz) to support N users for a given outage probability pout and cb/I0 requirement /3 for each user.
A case study analysis of a health and safety accident in the New Zealand workplace. The workplace should be related to your chosen discipline.
A step down chopper is to be used to supply power from 600 overhead wire to commutator motor on a trolley bus . The motor may be modeled as a generated direct voltage in series with a resistance of .2? and inductance of 25mH.
Modify the design in Figure 7.8 to provide separate instruction and data memories for the 8051: a 64K × 8-bit ROM for the instruction memory and a 64K × 8-bit asynchronous SRAM for the data memory.
