The magnetic circuit shown with a mean core length of 52 cm and a cross sectional area of 18 cm^2. the length of the air gap is 0.14 cm. Determine the battery voltage required to obtain a flux density of 1.2 T in the air gap. Use the magnetization curve?.
a. Determine the current I(t) required to produce the B-field 2cos(wt)(T) in terms of other variables, for a sinusoidal field of 60 Hz, and N=100 turns. b. Now assume that you have the above B-field generated inside the solenoid.
A 100μF capacitance is initially charged to 1000 V. At t1=0, it is connected to a 1kΩ resistance. At what time t2 has 50 percent of the initial energy stored in the capacitance been dissipated in the resistance
Actel Corporation manufactures an FPGA family called Act 1, which has the multiplexer based logic block. Show how the function f=w2w3'+w1w3+w2'w3 can be implemented using only one Act 1 logic block.
Two ways to implement a serial adder (A+B). it is necessary to modify the circuits to convert them to serial subtractors (A - B).Using the circuit to show the changes needed to perform A +2'scomplement of B.
Build a 4-to-1 MUX using some tri-state buffers and two inverters(NOT gates). (Hint: you can build a 2-to-1 MUX using some tri-statebuffers and one inverter and then combine several 2-to-1 MUXes tobuild a 4-to-1 MUX.)
The value of the capacitor from the high-voltage terminal to the tap point is 0.005µF. The tap point voltage is 4 kV. What is the value of the capacitor connected between the tap point and the ground terminal. What is the value of the tuning induc..
