A 4.0MΩ resistor is connected in series with a 5.0μF capacitor. The capacitor is initially uncharged. The RC combination is charged by a 9.0 volt battery.a. What is the change in voltage between t=RC and t=3RC?b. How long after being connected to the battery will the voltage across the capacitor be 9.0V?
The Y-Connected synchronous motor whos nameplate is shown in Figure 1 has a per-unit synchronous reactance of 0.9 and a per-unit resistance of 0.02. a.) What is the rated input power of this motor
If a frame is damaged then in this network the receiver sends back a request for retransmission. (For simplicity, assume all these requests arrive back perfectly at the sender). What is the mean number of transmissions required to successfully tra..
Compare these results with the ones for analog filter and comment. Notice that the frequency response of digital filter has linear normalized frequency in [0,f] when the bode plot gives a logarithmic frequency axis of different range.
A voltage divider has a 5 V source and two 150 kilo ohm resistors. What is the voltage across(a) an ideal voltmeter (b) a voltmeter with an input resistance of 10 mega ohms
Design a suitable amplifier using a combination of these stages. Your design should utilize the minimum number of stages and should ensure that the signal level is not reduced below 10 mV at any point in the amplifier chain.
Consider a pn junction diode biased at I(D) = 1mA. A sinusoidal voltage is superimposed on V(D) such that the peak-to-peak sinusoidal current is 0.05I(D). Find the value of the applied peak-to-peak sinusoidal voltage if n = 1.5. Repeat problem for..
Describe how three-position control might be used to cause a windmill to always face into the wind. The windmill is rotated with a bidirectional DC motor.
If the signal amplitude across the base-emitter junction is to be limited to 10 mV, what is the corresponding amplitude of vsig and v0 Find the open-circuit voltage gain Gvo and the output resistance Rout. Use these values first to verify the value ..
what single amount at the end of seven years is equivalent to a uniform annual series of %5000 per year for 12 years if the interest rate is 8% compounded annually
Two statistically independent random variables, X and Y, have variances of sigma^2 (X) =9 and sigma^2(Y) =25. Two new random variables are defined as: U = 3X + 4Y V = 5X - 2Y (a) Find the variances of U and V.
For a PMAC (permanent-magnet ac) machine, what would happen if the supplied frequency is not same with the rotating frequency of the rotor
The trees can be harvested early at reduced yield: the net profit is then $250T per $1,000 initial investment, for T in years. To the nearest whole year, at what T is the rate of return largest
