an electric motor operates at 220V rms ,60 Hz, draws 20A rms, and has a power factor of 0.75 lagging.
a) what is average power absorbed by the motor?b) what value capacitor should be connected in parallel with the motor to give a power factor of 1?
Write a report on Future Generation Telecommunication Technology.
Three capacitors are found that each have an impedance of -j2.0, and they are connected in parallel with the load in a wye configuration. Determine the power factor of the combined load as seen by the source.
Design an amplifier circuit which uses an OpAmp and is powered by dual 15 V power supplies, and which has the following characteristic at low frequencies: Vout = 3V1 - 5V2 1. State the information which is extracted from the equation.
a) What would be the value of the parity bits. b) If some of the bits get flipped in transmission and the following bits are received 1101 0101 0001 0010 1010 with the parity bits, can you detect the error. Can you correct it.
A first-order circuit, having a gain of 10 at dc and a gain of 1 at infinite frequency, has its pole at 20 kHz. Find its transfer function.
what is meant by "proactive" project management. Discuss ways in which to ensure that projects are being managed proactively. Investigate on the internet the features of Microsoft Project. Discuss why a project plan is not a Microsoft Project file.
Suppose that random samples of size 36 are repeatedly drawn from a population with mean 28 and standard deviation 9. Describe the sampling distribution X var.
Baseband digital trnamission and multi level coding, A baseband digital data link transmits polar binary NRZ current pulses at a rate of 1.0 Msps. The link uses ideal RRC filters with roll off factor r = 0.5.

Each player has 8 switches that have a value of 0 to 7 and the game has a 3-bit counter that will generate a random number between 0 and 7. The player that can come as close a possible to the random number
If a system has a unit-impulse-response of h(t) = 100t * e^(-20t) u(t) , where u(t) is the standard unit step function, then determine the transfer function H(f) for the system. What type of filter is this system (high-pass, low-pass, band-pass, ..
