An amplifier with an open-circuit voltage gain of -1000 and an output resistance of 100 Ω feeds a resistive load of 900 Ω. Negative feedback is provided by connection of a resistive voltage divider across the output and one-fiftieth of the output voltage fed back in serieswith the input signal. Determine the voltage gain with feedback. What percentage change in the voltage gain with feedback would be produced by a 50 per cent change in the voltage gain of the basic amplifier due to a change in the load? The loading effect of the feedback network can be neglected.
Write a reflection paper about electrical engineering in the bart station.
Derive the two-term including source match error correction formula. Note: For all of these derivations, you should identify your standards {match, short, open} but DO NOT assume anything about their values.
Assume that a given transformer is 100% efficient; that is, the power being supplied by the primary side is transported without loss to the secondary side. (Transformers are not 100% efficient. One can detect this by the heat that they radiate.)
How much energy in Kilowatt hours is initially stored in the battery If the battery costs $75 and has a life 0f 300charge-discharge cycle, what is the cost of the energy in dollarsper kilowatt hour Neglect the cost of recharging the battery.
Find the change in resistance of an electrical resistance strain gauge with a gauge factor of 2.0 and a resistance of 100 Ω when subject to a strain of 0.001.
Attenuation of received power with change in transmission frequency and distance between the antennas
(a) Determine a unit vector in the direction of Q at P(1, 2, 1) (b) Find the component of Q at P in the direction of PT where T is point (5, 3, -4) (c) Where is Q the same as the unit vector of \(a_{x}+11a_{y}+10a_{z}\)
How to calculate the number of indoor lighting fixtures ? (with an example)
view an electrical substation that delivers power to a manufacturing plant, you notice large boxes with two terminals connected by wires to the substation network. What might be one function of these large boxes
where ω0 is a constant, and Y, θ are statistically independent random variables. Assume that Y has a mean value of 3 and a variance of 9, and that θ is uniformly distributed from -π to π. Find the mean and mean-square value of the process.
An incandescent light bulb can be modeled as a resistor with a value of a few ohms. Imagine an incandescent light bulb goes out in your house. Using your trusty multimeter, how would you check if the bulb is bad and needs replacing
Write a C++ function which initializes its three reference parameters. The function should take an int, double, and string parameter and initialize them to 0 and the empty string ("").
