Question:
Two identical conducting plates, each having area A, are located at z = 0 and z = d.
The region between plates is filled with a material having z-dependent conductivity, σ(z) = σ0e-z/d, where σ0 is a constant. Voltage V0 is applied to the plate at z = d; the plate at z = 0 is at zero potential.
Find, in terms of the given parameters, (a) the resistance of the material; (b) the total current flowing between plates; (c) the electric field intensity E within the material.
Data are transmitted over a channel with a single-bit error probability of 10-12. If 1012 bits are transmitted, what is the probability of one bit error. What is the average number of errors expected?
If a circuit contains 3 automatic switches and we want that, with a probability of 95%, during a given time interval they are all working, what probability of failure per time interval can we admit for a single switch
The resistance of the coil is .4 ohm. The inductance of the coil is 2.4e-4 H. The rotor inertia is 2.0e-5 kg m2. The current to torque gain is 0.06 Nm/A. The friction torque is 0.18 Nm. A 12 V voltage source is applied to the motor.
