1. The flux linking a 600 turn coil changes uniformly from 100 mWb to 50 mWb in a time of 85 ms. Calculate the average emf induced in the coil.
2. An average emf of 350 V is induced in a 1000 turn coil when the flux linking it changes by 200 Wb. Determine the time taken for the flux to change.
Determine the transfer function of a second order Butterworth Lowpass filter with a 3dB cutoff of 5 Kilo Hertz. Design a circuit which realizes this filter using Sallen-Key configuration. Find all the values of the circuit elements and determine t..
A combinational logic circuit has 18 binary inputs. Assuming it takes 50 ms to input one test pattern and record the circuit's output, how long will it take to do an exhaustive test
The summing amplifier in Figure P14.15 has an op-amp with open-loop parameters: AOL = 2 × 103, Ri = ∞, and Ro = 0. Determine the actual output voltage as a function of vI1 and vI2. What is the percent error from the ideal value?
A piece of germanium doped with 1016 cm-3 shallow donors is illuminated with light generating 1015 cm-3 excess electrons and holes. Calculate the quasi-Fermi energies relative to the intrinsic energy and compare it to the Fermi energy in the absen..
A 230V, 60Hz voltage is applied to the primary of a 5:1 step down, center tapped transformer used in the Full-wave rectifier having a load of 900Ω. If the diode resistance and the secondary coil resistance together has a resistance of 100Ω.
Find the gains of the IP regulator and the bandwidth of speed regulation loop with the IP regulator. In that gain setting, plot the following responses.

A Si sample is doped with 10^17 As atoms/cm^3. What is the equilibrium hole concentration P0 at T=300K?
When one push button is pushed, the selected soda is dispensed and the machine returns to its initial state. One other feature is that an LED comes on to warn the user that two quarters are not available for change, so if a second $1 bill is inser..
Two charged concentric spherical shells have radii 10.0cm and 15.0cm. The charge on the inner shell is 4.00X10^-8C, and that on the outer shell is 2.00X10^-8C. Find the electric field (a) at r = 12.0cm and (b) at r = 20.0cm.
How would you orient a loop antenna in order to obtain maximum signal from an incident electromagnetic wave which has its magnetic field linearly polarized in the north-south direction?
