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 each conductor is 0.0002 ohms per metre. Find the voltage necessary at feed point to maintain 250 V
i). At the far end
ii). At the mid-point of the distributor
2). Derive an expression for the power loss in a unifoimly loaded distributor fed at one end.
A constant (dc) current i(t) = 3 mA flows into a 51-F capacitor. The voltage at t = 0 is v(0) = -21V . The references for v(t) and i(t) have the passive configuration. A) Find the power at t=0. B) State whetehr the power flow in into or out of the ..
Briefl y explain the improvements introduced by GAL over the existing PAL and PLA devices. Why is GAL fi ne for implementing sequential circuits while the other two are not?
Explain why the ionic contribution to the dielectric constant vanishes at frequencies greater than about 1GHz. 2. What is the relative permeability of a magnetic core material if the magnetizing field, H, saturates the core material?
Choose an application in business or industry that uses RL or RC circuits in its operation.
An inspector selects an item for inspection according to the outcome of a coin flip: the item is inspected if the outcome is head. Suppose that the time between item arrivals is an exponential random variable with mean one.
In a matched CMOS inverter in which Vtn = - Vtp = 0.5 V, VDD = 1.8 V, kn = kp = 600 uA/V^2 and fabricated in a 0.13 um technology, use the average current method to determine W/L ratios such that the propagation delay tp is smaller
A pulsar lies 1000 light years from Earth. The average plasma concentration is 1 el/cc. Using the plasma dispersion relationship for group speed, what is the group delay between a pulsar pulse received at 1 GHz and at 800 MHz
