A power factor correction capacitor bank, withnegligible resistance, draws a current of 625 amperes whenconnected to its 480 VAC, 60 Hz source.Calculate the capacitive reactive power of the capacitor bank.
Given an 16-bit A/D converter and a ± 5 volt incoming signal. Suppose you want a minimum count on the A/DC toequal -5 V and a maximum count to equal +5V. a) How many states can this A/DC take on
A 50HP single phase motor operates from a 480V, 60HZ supply. When delivering full rated power the motor efficiency is 89% and the power factor is 0.78 lagging. Determine the full load current.(Hint: 746W=1HP)
A 220V , 13.47KVA, 0.707 lagging power factor load is in parallel with a three phase wye- connected round rotor synchronous motor having a synchronous reactance of 1.27W. The motor draws 33KW at apower angle of 30 degree.
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.
Suppose that we are designing a cardiac pacemaker circuit. The circuit is required to deliver pulses of 1-ms duration to theheart, which can be modeled as a 500-Ω resistance. The peak amplitude of the pulses is required to be 5 V.
A first-order allpass filter impulse response is given by h(t) = - d(t) + 2e^(-t)*u(t) a) find the zero-state response of this filter for the input e^(t)*u(-t). b) sketch the input and the corresponding zero-state response.
A satellite is operated at C-Band (6 GHz in the uplink and 4 GHz in the downlink) for video broadcasting. Calculate the free-space loss experienced at this frequency, if the satellite is in geostationary orbit (GEO), located at 36 000 km above gro..
A battery is charged. The relationship between the charging current, i amperes and the time, t hours passed, is given by the formula:
Two input capture events occur at counts 0xBA47 (first event) and 0x42B3 (second event) of the free-running counter. How many counts have transpired between these two events
Consider a PNP BJT optimum designed for low voltage high current gain. (a) Draw energy band diagram with proper labeling with VCB= -0.7V, VEB= 0.7V. Which mode is the BJT operated in (b) Plot excess minority charges stored in each region with pro..
Discuss the attributes of professional and technical presentations. What are some of the characteristics that may differentiate these types of presentations from others.
Two charges are held fixed in an x-y plane. Charge Q=-1*10^-9 C is located at the origin, q=3*10^-9 C is located at (0,2). Determine the voltage (v_ba) between point 'b' located at (3,0) and point 'a' located at (1,0).
