1. Using Mesh Technology, find in the circuit of figure 1.
2. Using Krichhoff's laws, calculate the current delivered by the battery shown in figure 2.
1. for the waveform shown below obtain expressions for fourier components for fundamental 5th 7th and 11th elements
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.
Given a 1-phase 50 kVA 12.47 kV pf = 0.8 lagging static load a. Modeling the load as constant complex power, determine the correct value for S and I. b. Modeling the load as constant complex impedance, determine the correct value for Z and I.
In transformer designs, often you can find an air gap in the core. In all the electric machines, there is an air gap between the stator and rotor. In both cases, flux will go through both core material and the air gap.
Help with problem in Control signal processing class, Consider the unity-feedback control system whose open-loop transfer function is
a) The number of turns on its high side. b)The turns ratio when it is used as a step-down transformer. c) The turns ratio when it is used as a step-up transformer.
Define induction motor and explain its principal of work
A continuous time system is described by y(t) = t tan(x(t)). The continuous time system is sampled every T seconds to obtain a discrete time system y[n]. determine the mathematical expression for y[n].
An AM signal is written as xc(t) = Ac (1+ µx(t))cos(2pi*fc*t) where fc is the carrier frequency, Ac is the carrier amplitude, µ is the modulation index, and x(t) is the baseband message signal. We assume that x(t) has absolute bandwidth W
Write a MATLAB script to determine the probability P[X+Y=7]. Use a "for" loop to run simulation fifty times with n = 10000. Plot the 100 estimated probability values along with the theoretical result of P[X+Y=7].
Write down the principle of energy conversion and give an example for single and double excited system.
A motor scooter travels east at a speed of 9 m/s. The driver then reverses direction and heads west at 20 m/s. What was the change in velocity of the scooter?
