A l / 2 dipole, with a total loss resistance of 1 ohm, is connected to a generator whose internal impedance is 50 + j25 . Assuming that the peak voltage of the generator is 2V and the impedance of the dipole is 73 + j42.5 , find the power(a) Supplied by the source (real)(b) Radiated by the antenna(c) Dissipated by the antennaNote that: the dipole impedance does not include the loss resistance.
A copper busbar 10cm wide, 5 mm thick, and 10 m long carries a current of 2kA, Calculate the voltage drop if the temperature of the busbar is 120 degree. What is the power loss per meter
A system is needed to measure flow, which continuously cycles between 20 and 30 gal/min with a period of 30 sec. The required output is a voltage varying from -2.5 to +2.5 V for the cycling flow range. The sensor to be used has a transfer function..

A DC motor is rated at 230V, 27.5A at normal full load. It turns at 1750rpm under rated conditions. It has total armature resistance of 0803 ohms, and it is desired to hold its maximum starting current to 150% of normal full-load current.
The voltage across a certain load is V =1200*sqrt(2)*30 V, and the load impedance given by Z = 40 j30 ohms . Is the load inductive or capacitive Determine the power factor, complex power, real power, reactive power, and apparent power delivered to..
Write a program to compute the average of an array of N 8-bit numbers and store the result at $1001. The array is stored at memory locations starting from $1010. N is no larger than 255. Assume N is stored in the memory location $1000.
The power transfer in a transmission line is governed by the equation P = VS * VR * sin\(\delta\)/X line. Basedon this equation what is the maximum power transfer that can be achieved, and what is its value if VS =VR = 1.0p.u
