(a) Formulate node-voltage equations for the circuit in Figure.
(b) Solve for vx and ix.
(c) Verify your results using Multisim.
Vout=3.5v1 +(-1.5)v2 . The input impedances should be: input 1: 20k, input 2:∞.Youmay need to use 2 or more op-amps (inverting, noninverting,summing, differential, voltage follower...). Show calculations anda drawing of the op amps used.
An AC source which produces a peak voltage of 169.7 V is connected across a resistor of 10 Ω. How much energy is dissipated in the resistor in 5 s?
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.
Which of the transistor currents is always the largest? Which is always the smallest? Which two currents are relatively close in magnitude?
An LC circuit consists of a capacitor, C = 3.16 ?F, and an inductor, L = 5.80 mH. The capacitor is fully charged using a battery and then connected to the inductor. An oscilloscope is used to measure the frequency of the oscillations in the circui..
A 37.5-kVA, 6900-230V, 60Hz, single phase transformer is operating in the step down mode at rated load, rated voltage, and 0.68 power factor lagging. The equivalent resistance and reactance referred to the low side are 0.0224Ω and 0.0876Ω
the bridge circuit is energized from a 21 V dc source. the bridge is balanced when R1 = 800Ω, R2 =1200Ω, and R3 = 600Ω. a) what is the value of Rx b) how much current(in milliamperes) does the dc source supply
one question during each cycle the velocity v in mms of a piston is v 6t - 6t2 where t is the time in sec. find the
refer to the system block diagram. if power ps10w power gain factor g1150 and power gain g214 db find the maximum
Fuel Cell produces current by using H2. Anode reaction: H2-->2H+ + 2e- Cathode reaction: 4e- + 4H+ +O2 --> 2H2O. The rate at which Hydrogen enter the fuel cell is given as 5 L/min. The temperature is constant at 300K.
The name plate of a squirrel-cage four-pole induction motor has the following information: 25 hp, 220 volts, three-phase, 60 Hz, 830 rev/min, 64A line current.
