Consider an industrial load that absorbs 40 kW of power with power factor 0.8 lagging from a 60-Hz transmission line of voltage VL= 240<15° V rms VL . To improve the power transmission efficiency, a bank of capacitors having combined capacitance 220 micro(uF) is placed in parallel with the load. Find the effective power factor at the load.
From what distance must the electron be red if it is to just fail to strike the plate?
Determine the response of the system when aunit step is applied at input.
an Armstrong indirect FM modulator to generate an FM carrier with a carrier frequency of 96 MHz and deviation of f=20 KHz. A narrowband FM generator with Fc=200 KHz and adjustable deviation f in range of 9 to 10 Hz is available.
Resisitive load, A 4:1 step down transformer uses a 60Vac source on the primary windings.
Two amplifiers(CS) connected in cascade. The input voltage to the first stage has a source voltage Vsig and Rsig= 100KOhm. Rv=10KOhm AND IS CONNECTED TO THE DRAIN OF THE SECOND STAGE. BOTH TRANSISTORS HAVE Id=.25mA and Vov=.25V
A delta-wye connected three-phase transformer is rated at 38 MVA with primary and secondary line voltage ratings of 345 and 125 kV, respectively. The transformer p.u. reactance is 10%, the p.u. no-load current is 0.1.
Can you write a part of project which is about developing a schedule of power substation on primavera (P6), focusing on the Changes that will happen based on the following:
calculate the average signal-to-noise (SNR) in decibels (dB) Assume equal numbers of binary 0s and 1s.
Suppose a turbine is used for generating electricity, estimate the ratio of powers generated by the same speed water and air. (Water density=1g/cm3, air density =1.2kg/m3)
This solution shows how to work from a given circuit implementation (a J-K flip flop circuit design) to derive the Boolean Logic and in so doing so simplify such logic using Boolean Algebra rules
A junction employs Nd = 8x 10^17cm^-3 and Na= 2 x 10^ 17 cm^-3. The device is at 300K. (a) determine the majority and minority carrier concentrations on both sides (b) Calculate the built-in potential at (i)T=250K (ii)300K
(b) If the molecular weight of bombykol is 238.4 amu, what is the molecular formula (c) If 5.698 g of bombykol is burned in excess oxygen to form 16.83 g of CO2 and 6.452 g of H2O, how many grams of carbon were present in the original sample
