1. A toroid has an mmf of 845 At applied to it. If the mean length of the toroid is 15 cm, determine the resulting magnetic field strength.
2. A magnetic field strength of 2500 At/m exists in a magnetic circuit of mean length 45 mm. Calculate the value of the applied mmf.
Determine the range of stable gain for the following system using the Routh test. s4 + 3s3 + 12s2 + (K - 16)s + K = 0
The armature, frame, and core of a 12-V DC control relay are made of sheet steel. The average length of the magnetic circuit is 12 cm when the relay is energized, and the average cross section of the magnetic circuit is 0.60 cm2.
Devise a detailed algorithm for a ring with p nodes so that each node would atttain the final sum of original node values. Determine the worst case communication steps for the algorithm.

design a circuit to compute F=(A*B*C) +3*D+12,A,B,C and D are 16 bit inputs and F is a 16 bit output. Use 16 bit multiplier and adder components, and ignore overflow issues.
a 9.1 v zener diode exhibits its nominal voltage at a test current of 28 mA . at this current the incremental resistance is specified as 5 ohms . find Vz0 of the zener model . find the zener voltage at a current of 10 mA and at 100 mA.
Three two-input "AND" gates have their outputs connected to an "OR" gate. The first "AND" gate has each of its inputs at logic HIGH level. The second "AND" gate has each of it's inputs at logic LOW level.
Consider a p-type semiconductor substrate with Na =10^15 cm^-3. A region of heavily p+ doped material is formed by ion implantation as shown in the sketch below.Derive an expression for the built-in voltage under equilibrium conditions.
