Objects A and B have the same mass of 3.7 kg and are at their melting points. They melt when 3.9 × 104 J of heat is added to A and when 11 × 104 J is added to B. (a), (b) Determine the latent heat of fusion for the substance from which each object is made. (c) Find the heat required to melt object A when its mass is 7.4 kg.
In this project we will consider the control of a synchronous generator supplying electricity to the grid.
Write a single source file which implements all of the following problems. All problems must be solved using nested loops. Just writing lots of couts to solve the problems will result in zero credit.
A PLL frequency synthesizer has a variable -modulus prescaler of M=10/11 and divider ratios of the A and N COUNTERS OF 40 and 260. the reference frequency is 50khz. what are the VCO OUT PUT FREQUENCY and the minimum frequency step increment
A shunt regulator utilizing a zener diode is biased on through a 100-ohm resistor. Determine the change in the regulated output voltage for the two situations below a) VI changes +2.0 V, ILoad constant b) ILoad changes +100 mA, VI constant
A balanced three-phase inductive load is supplied in steady state by a balanced three-phase voltage source with a phase voltage of 120Vrms. The load draws a total of 10kW at a power factor of 0.9.
What happens to the propagation delay of the N-bit full adder as N is increases from 2 bits to 32 bits Compare and contrast this method of building an adder with the carry look ahead method described in your textbook
Let c(x) = 1 - x2/2! + x4/4! and s(x) = x - x3/3! + x5/5! be approximations to cos(x) and sin(x) respectively. What are the relative and absolute errors in using these formulas for x = -2, -1, 0, 1, 2 degrees
Consider the function f which has four inputs a,b,c,d and one output such that the output is a 1 if and only if the number of 1s in the inputs is even. (a) Write the canonical product-of-sums expression for f. Do not use the shorthand notation
A load is drawing 10 A rms when connected to a 1200 V rms supply running at 50 Hz. If the source is operating at a lagging PF of 0.9, calculate (a) the peak voltage magnitude; (b) the instantaneous power absorbed by the load at t = 1 ms
A ripple carry adder is made of full adder cells each having 1 unit of combinational delay. To convert a four-bit ripple carry adder into a four stage pipeline adder proceed as following.
Three identical impedances of (12+j15)ohms are connected in wye to a 550V balanced three phase source. Determine, (a)the magnitude of the line currents. (b) the total power dissipated for the three phases. (c)the total reactive power. (d)the power..
Consider two Si samples; one is p-type doped to 1018/cm3 acceptor atoms and the other one n-type doped to 1015/cm3 donor atoms at room temperature (300K). a. Draw the band diagram associated with p-type and n-type semiconductors, noting the various..
