The line voltage and current delivered to a balanced 3-phase Wye- connected resistive load bank is measured and found tobe 415 V and 30 A respectively. 1) What is the value of voltage across on phase of the load bank?
2) What is the value of current across on phase of the load bank?
3) What is the value of the total kW power delivered to the load bank?
4) If a single wattmeter is connected to meter the voltage andcurrent of any one phase, what would its kW reading be?
Two infinitely long coaxial cylindrical surfaces, r = a and r= b (b > a), carry surface charge densities Dsa and Dsb,respectively. (a) Determine the electric field intensity everywhere. (b) What must be the relation between a and b in order that Eva..
Calculate the efficiency of transmission at the IP level. Assume no options for the header and no errors. Calculate the efficiency of transmission at the data link layer. Assume no options for IP header and Ethernet-II format are used at the d..
Design a synchronous circuit that implements a 4-bit decade (modulo-10) counter (0000,0001, ..., 1001, 0000,...) a. Fill in a transition table (using don't cares for undefined next states).
Design a 2-bit multiplier using 2-input AND gates along with 2-input OR gates and inverters. Hint: start with a truth table and keep in mind that there are four inputs and four outputs. The numbers to be multiplied can be represented
The power factor of the added load is to be adjusted so that the overall power factor of the factory is 0.96 lagging. The factory is fed from a line having an impedance of 0.02 + j0.16 O. The voltage at the factory is maintained at 480 V(rms).
The prime mover rotates the armature at a speed of 1000 rpm. Determine the no-load voltage, the full-load voltage, and the torque required by the prime mover at full load if the full-load power required by the load is 3 kW
A digital system has a clock generator that produces pulses at a frequency of 8 MHz. What is the frequency of QB
Data at a rate of 2 Mbps is to be transmitted via a pass-band communication system whose carrier frequency is 500MHz. A binary antipodal system with roll-off factor of 0.2 is used for this communication.
A sequential circuit has two inputs, w1 and w2, and an output z. Its function is to compare the input sequences on the two inputs. If w1 = w2 during any four consecutive clock cycles, the circuit produces z=1; otherwise, z=0. For example
If an AM signal has an un-modulated carrier voltage Vc=A volts(pk) and a load resistance RL of B ohms. How to calculate the Pc (Carrier Power) If the modulation index is known as m, how to calculate the Sideband Power (Psb)
