An RLC parallel circuit is connected to a 240 volt, 60 Hz line. The apparent power of the circuit is 3,865 VA. The inductive VARs are 1,892 and the capacitive VARs are 1,563. What is the resistance of the resistive branch?
Given the digital filter transfer function H(z)=1-z^-1 , what is the step response (that is, the input to the filter is unit step sequence u(n) ) of the filter A. y(n)= delta(n)+delta(n+1) B. y(n)=u(n-1) C. y(n)=u(n)-u(n-1) D. y(n)=u(n-2)
create the most fantastic holiday light show in your neighborhood. You have purchased 100 sets of lights with each set having 100 bulbs connected in series. Each bulb has 1 Ohms of resistance and requires 0.01A before it will turn on.
A transmission line of char. Impedance 100ohm is used to match a 50ohm section to a 200 ohm section. if the matching is to be done both at 429MHz and 1GHz the length of the transmission line can be approx?.

A circuit board with a dense distribution of integrated circuits (ICs) and dimensions of 120 mm by 120 mm on a side is cooled by the parallel flow of atmospheric air with a velocity of 2 m/s.
Assume there are five numbers stored in locations 20 to 24. Write a machine language program to add these numbers and store the result in location 25.
A box of mass 20kg is slid down a ramp inclined at 20 degree with an initial speed of 5 m/s. If the box stops after 10 m, what was the coefficient of kinetic friction between the box and the ramp
2 coils are 80% magnetically coupled for a magnetic system. Suppose that coil 1 is excited by AC voltage V1=200 v with current I1=1 A, all in rms values at 60Hz, while coil 2 is open and receives an induced voltage V2 = 50 v in rms.
