Two coils wound on a common core have L1 = 0.2 H, L2 = 0.5 H, and M = 0.1 H. The currents are i1 = exp( -1000t) A and i2 = 2 exp( -1000t) A. Both of the currents enter dotted terminals. Find expressions for the voltages across the coils.
Design the low pass filter with the 3 dB point at 1Khz. DC gain is 0 dB. use the C value as 100 uf and input ac magnitude 1 V. use the AC simulation between 1 mHz to 1 Khz.
The donor concentration in a silicon sample at 300K is ND = 1.2 x 1015 cm-3. 1 x 1016 cm-3 acceptor atoms are added to form a compensated p-type semiconductor so that the Fermi level is 0.26 eV above the valence band edge.
Find the permittivity of a parallel-plate capacitor if its capacitance is 100 ?F, the dimension of each rectangular plate is 1cm by 0.5cm, and the distance between the plates is 1mm.
A studen wants to constrcut a 1 F capacitor out of two squareplates for a science fair project. He palns to use a paperdielectric (εr= 2.5) that is 8x10-5 m thick. Thescience fair is to be held in Astrodonem. Will his capacitor fit inthe Astrodome
Derive the transfer function for a system with an function u(t) and an output function x(t) described by the following differential equation; d^3x/d^5d^2x/dt^2+17d^x/dt+13=d^2u/dt+6
The Finite-Difference Time-Domain (FDTD) method is a computational electromagnetic technique for solving for the electric and magnetic fields in arbitrary spatial domains in the time domain
Box 1 contains 5 red, 6 white, and 9 blue balls. Box 2 contains 7 red, 8 white, and 4 blue balls. A ball is withdrawn at random from Box 1 and placed in Box 2. Then, a ball is taken at random from Box 2.
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.
What are the rated current and internal generated voltage of this generator? What field current does this generator require to operate at the rated voltage, current, and power factor?
A gas of density 1.83kg/m^3 and a viscosity of 1.5 x 10^-5 Pa.s is pumped through the tower. The volumetric flow rate of the gas at the entrance is 20 m^3/hour. a. Calculate the pressure drop at the exit of the packed bed.
Ib is 15uA in a circuit where an NPN transistor has an Av of 75 and VCE is 10 when Vcc is 25 and Beda DC is 75 and the Ic is 1.125mA, What would Rc be, assuming Ve=0
A variable-frequency voltage source of value 12cos(wt) drives a network with a resistor of value 12 ohms, an inductor of value 50mH, and a capacitor of value 5uF, all in series, in that order.
