An ac circuit with 4.157kv 60hz with a load of 2880 kva load and pf=.8 lagging find all the currents (6 total), also draw the diagram.
Given: A 13.8 kV circuit has a load of 6000 kVA with a lagging power factor of 0.8. Required: How much capacitive reactive power is needed to correct the power factor to 0.92 lagging
The power amplifier in a home theater amplifier has an output power of 200 watts. Assuming a Class B amplifier with the maximum theoretical efficiency is used, find the DC power delivered to the amplifier.
3) What factors started the decline in the nuclear power industry, and what events essentially ended new construction of nuclear power plants 4) What are three advantages of using AC power over using DC power
Silicon at T = 300 K is doped with arsenic atoms such that the concentration of electrons is n0 = 7 x 1015 cm -3. (a) Find Ec - EF. (b) Determine EF - Ev. (c) Calculate p0. (d) Which carrier is the minority carrier
A 100-KVA, 2500/125-V, 50-Hz, step-down transformer has the following parameters: RH= 1.5 ohm ,XH= 2.8 ohm , RL=15 m omh XL = 2.m ohm, ,RcH=3 k ohm, XmH = 5k ohm. The transformer delivers 85% of the rated load at a terminal voltage of 110V
A cable TV receiver has an input impedance of 200?. The cable TV distribution system uses RG-6 cable. This cable has a characteristic impedance of 75?. Design an impedance matching stage to maximize the power transfer from the wire to the receiver..
With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
A Whetstone bridge has a strain gage in the lower right leg with a 120 ohm nominal resistance. It is mounted on steel with a Modulus of Elasticity equal to 30x106. The other resistors are equal to 120 ohms.
