1. A 250 m, 2 wire D.C distributor fed from one end is located uniformly at the rate of 1.6 A/metre.
The resistance of eath conductor is 0.0002 ohms per metre.
Find the voltage necessary at feed point to maintain 250 V
i). At, the far endii).At the mid-point of the distributor
2). Derive an expression for the power loss in a uniformly loaded distributor fed at one end.
You are evaluating the feasibility of adding an injection molder to fabricate plastic sporks (everybody’s favorite harmless utensil) for the US Facility for the Criminally Insane. An injection molder will cost $1,200,000 installed.
An EEG signal from a healthy adult contains clinically relevant frequencies in the range of 0 to 45 Hz. The frequency bands are generally grouped as delta (0.5-4 Hz), theta (4.5-8 Hz), alpha (8.5-13 Hz), and gamma (30-45 Hz).
The internet connection speed at any time from your home can depend on the amount of overall internet trac at that time. Let the random variable X denote the speed of connection in megabits per second (MBPS).
An FM receiver is modulated with a signal having a baseband bandwidth of 15 kHz and the maximum frequency deviation is 45 kHz. Assume that preemphasis is added with a 3-dB boost frequency of 5 kHz.
The diagram below is the schematic of a protection system for a 33/11kV double transformer substation in which the 33kV switchboard and the 11kV switchboard are at the same location.
What is the The Main Difference between Active and Passive Components ( Explanation with Examples required )
A "ferrite" having a relative permeability of 50 H / m, that operates with flux densities sufficiently small, may be considered a single material. If the magnetic flux density in the material is B = 0.05 T, H and M. halle How to compare the values
construct a vertical line on your I versus V graph at the point V=5V. this line will intersect each of the sloping lines at two separate points. explain the significance of these intersections.
If the attenuation coefficient for the wave in equation E =Eoe-αzsin(ωt - kz) has the value 2x 10-5 cm-1, compute the power loss in dB for1 km. Compute the fractional loss for 1 km.
Allowing a safe value of field stress of 10 MV/m, determine (a) the required thickness of the ceramic dielectric, (b) the area of plate required if the relative permittivity of the ceramic is 10, and (c) the maximum energy stored by the capacitor.
Design each of the circuits specified in the Procedure section of this lab. Your design should attempt to get within § 5 % of the specified gain. All designs are to use standardcommercial 5 % resistors. You may only use a single resistor for each ..
