Consider a hollow spherical conductor with total charge +5e. The outer and inner radii are a and b, respectively.
(a) Calculate the charge on the sphere's inner and outer surfaces if a charge of -3e is placed at the center of the sphere. (Use the following as necessary: e.)
(b) What is the total net charge of the spherical shell? (Use the following as necessary: e.)
A unit for a telecommunications system is to be designed so as to have a minimum availability of 0.9994. The MTTR (mean time to repair) for the unit is estimated to be 24 hours.
A circular line charge of uniform line charge density q(C/m) is located in z=0 plane with its center at the origin. Determine, a. The electrostatic potential V at a point along the z-axis (0, 0, z) b. The electrostatic field E a point along the z-axi..
What is the maximum data rate possible for a standard telephone circuit with an SNR of 1023 and BW of 3 KHz using 8 bits per symbol
A 3-bit binary counter counts for 0 (000) to 7 (111). The counter moves to the next state with an input of x = 0 and stays in the same state with an input of x = 1. a. Draw the State Table and State Diagram for this 3-bit binary counter.
use GPS and they are useful for many reasons. GPS receivers use signals from more than three satellites so that cheap quartz clocks can be used instead of expensive atomic clocks. The quartz clocks tend to drift up to + or -1 ns/s.
The difference in voltage (Bat A - Bat B) should be displayed on a +5V - 0 -5V meter. Each volt on the meter display should correspond to 10 mV of battery difference. Include your choice for all components and power supply voltages.
