A factory has an electrical load of 1600 kW at a lagging power factor of 0.8. An additional variable power factor load is to be added to the factory. The new load will add 320 kW to the factory. The power factor of the variable power factor load is to be adjusted so that the overall power factor of the factory is 0.96 lagging.a) What is the reactive power associated with the added load?b) Does that load absorb or deliver magnetising vars (reactive power is also sometime referred to as magnetising vars. Inductors absorb magnetising vars and capacitors deliver magnetising vars)c) What is the power factor of the adjustable power factor load?d) If the voltage at the input is 2400 V(rms), what is the magnitude of the current into the factory before the adjustable load?e) What is the magnitude of the current with the adjustable load?
The voltage V across a semi conductor in a computer is given by V= aI+BI^2, where I is the current (in A). If a 24 V battery is conducted across the semi conductor, find the current if a=4 ohms and B= 0.5 ohms/A.
Consider unsteady diffusion across a membrane of thickness L. Initially, the concentration of solute in the membrane is zero. At time zero, the concentration at x=0 is raised to C0 and the concentration at x=L is maintained at zero.
Explain the process of processor development
A) What is the rms current in the circuit B) The primary side of the transformer has 20 times as many turns as the secondary side. What is the rms voltage across the primary side of the transformers
Find the associated answers for: total circuit impeadance (Zt), Current source (RMS), Vc (RMS) w/ power factor, Vr (RMS), all in complex form/ rectangular form. Remember each question has to be done three times, one for each frequency.

a parallel plate transmission line is made up of perfect conductors of width w = .2m and d = .01m. The medium between the plates is a diaelectric of epsilon = 2.25*(epsilon not) and mu = mu not. For a uniform plane wave propagating down the line
A charge density of ohm Coulombs per square meter is uniformly distributed over a thin and very long cylindrical shell of radius a. You want to know the electric flux density field D and the electric field E generated by this charge at all points ..
A trough is 8 feet long and 1 foot high. The vertical cross-section of the trough parallel to an end is shaped like the graph of y=x^{8} from x=-1 to x=1 . The trough is full of water. Find the amount of work in foot-pounds required to empty
