Explain Loads - Generation and Absorption of Reactive Power
A load at 0.95 power factor implies a reactive power demand of 0.33 kVAr per kW of power. When planning a network, it is necessary to assess the reactive power requirements of all the loads and to check whether the available generators are able to meet the required VArs for the extremes of load to be expected.
Q. Applications of operational amplifiers? An op amp along with a few external components (resistors and capacitors) is capable of performing many different operations-hence th
