Two three-phase wye-connected loads are in parallel across a three-phase supply. The first load draws a current of 20 A at 0.9 power factor leading, and the second load draws a current of 30 A at 0.8 power factor lagging. Calculate the following:
a. The transmission line current
b. The power factor of the load
c. The real power supplied by the source if the line-to-line voltage of the transmission line is 400 V
Find the current, the power and the power factor when it is supplied by 50V, 50Hz supply.- What are the values of R and L in the circuit?
how does Intel's architecture differ from MiPS?
In a binary digital communications systems, the bit energy required at the receiver input terminals is 50x10^-18 JOther parameters are as follows: Gt(dB)=24 dB Gr(dB)= 26 dB f= 10GHZ d=40,000 km
The power supplied by a certain battery is a constant 6.0 W over the first 5 minutes, zero for the next 2 min, a value that increases linearly from zero to 10 W during the next 10 minutes, and a power that decreases linearly from 10W to zero in th..

a clean nickel surface is exposed to light of wavelength of 235nm. what is the maximum speed of the photoelectrons
The AND gates should have no more than 3 inputs and the OR gates should have no more than 4 inputs. The one-bit full adder should accept two one-bit inputs and carry-in and should produce one-bit sum and carry-out.
Show that a Miller integrator implemented with an op amp with open-loop gain A0 has a low-pass STC transfer function. What is the pole frequency of the STC function. How does this compare with the pole frequency of the ideal integrator.
