1. A conductor, when placed at right angles to a magnetic field of density 700 mT, experiences a force of 20 mN, when carrying a current of 200 mA. Calculate the effective length of the conductor.
2. A conductor, 0.4 m long, lies between two pole pieces, with its length parallel to the pole faces. Determine the force exerted on the conductor, if it carries a current of 30 A, and the flux density is 0.25 T.
The cylindrical surface ρ = 8 cm contains the surface charge density ρs = 5e -20|z| nC/m2. (a) What is the total amount of charge present. Not so concerned about the answer but more about the process.
Air enters an adiabatic nozzle at 3 atm pressure and 100oF and emerges at 1 atm and 30oF. The inlet velocity is negligible. What is the discharge velocity
constructed using standard value resistors a. Without making a single calculation, which resistive element will have the most voltage across it Which will have the least b. Which resistor will have the most impact on the total resistance.
Using singularity functions, find the magnitude and location of the maximum bending moment for the beam and loading shown.
The network voltage is 27 kV. The generator operates with an induced voltage, which is twice the rated line-to-neutral voltage. Calculate the power angle if the network receives an inductive reactive power of 50 MVA.
Do you think that an electric automobile based on capacitive energy storage is feasible?
Discuss how a shift register differs from a counter and how flip flops are used in counters and shift registers. Also discuss different applications of counters and shift registers.
For the circuit of given figure, find Vab if (a) k = 0 and (b) k = 0.01. - Do not use network theorems to simplify the circuit prior to solution.
If a unity gain (Avo=1) buffer amplifier with 1 M ohm input resistance and 10 ohm output resistance is interposed between source and load, what do the output voltage and power levels become. For the new arrangement, find the voltage gain from sour..

If we have a transfer function T(s) = |Z(s)|/|P(s)| and we had a pole at s=-500; Then the magnitude would be sqrt(500^2 + w). So how does that not decrease the magnitude of the transfer function at frequencies below 500
(a)find the work done in moving a point charge +2C from (2,0,0) to (0,2,0) and then from (0,0,0) to (0,2,0). (b)find the work done in moving a point charge +2C from (2,0,0) to (0,2,0) along the straight-line path joining the two points.
