A pot with a total range of 350° is supplied with 5 Vdc. The output of the pot is converted to binary with an 8-bit ADC (which is also referenced at 5 Vdc). Find the 8-bit binary output of the ADC for a pot angle of 60°.
Two parallel connected 10 kV to 120 V 60 Hz single phase transformers supply a varying load. When the total secondary load current is 250 A at 0.85 PF lagging, determine the secondary current and operating PF of each transformer.
you are to design a serial sequence detector. your design will take in a clock reset and a one-bit data signal. your
Calculate the gain of an inverting amplifier with Rs = 100kO and Rf = 500kO. Assume the op amp is ideal. Calculate the gain of an inverting amplifier with Rs = 100kO and Rf = 500kO.
In a certain crystalline material the vacancy concentration at 25*C is one-fourth that at 80*C. At what temperature would the vacancy concentration be 3 times that at 80*C 2. Suppose one attempts to add a small amount of Ni to Cu in an effort to cr..
the power deliverd to a three phase Y-connected load is 3kw and the line-line voltage is 380v the load power factor is 0.85 lagging. determine the load current and impedance
the output voltage of battery drop from 6V .With no load to 5.2V with a load current of 400mA. calculate the internal resistance.
Write a function 'charges' that computes the total charge for a customer based on the GB of data the user uses per month. The function should also calculate the average cost per MByte of data (rounded to the nearest cent).
Find the magnitude of the current density in a sample of silver for which σ=6.17x10^7 S/m if: a) The electric field intensity is 1mV/meter. b) The same is a cube 2.5mm on a side having a voltage of 0.4mV between opposite faces.
A three-phase delta connected load has a phase resistance of 15 ohms and a phase reactance of 17 ohms when connected to a 480VAC 60HZ line. What is the phase impedance, phase current power factor, and total power delivered to the load
A certain 100-watt light bulb costs 75 cents and lasts for 120 hours. Another longer-lived 100-watt light bulb costs $1.20. How much longer would the more expensive bulb have to last to make it a "good buy"
Compare the power contained in the sidebands to the total power in the modulated signal. What is the power efficiency in this AM scheme and calculate the PEP supplied by the AM transmitter - Write an expression for the normalized modulating signal.
An ideal 3 phasemachine runs at 1800 RPM with a torque or 20 Nm. It is connected to a 220 V line-to-linesource and draws a current of 14 A. Determine the power factor and the per phase magnetizing reactance for the machine.
