Gamma Electronics Gamma Electronics is considering the purchase of testing equipment that will cost $800,000 to replace old equipment. Assume the new machine will generate after-tax savings of $400,000 per year over the next four years. If Gamma Electronics has a 14% cost of capital, what's the NPV of the investment? $365,485 $800,000 $1,165,485 $185,605 Science. All rights t in order 1.1 What is Power Electronics? [1] Power Electronics is the study of electronic circuits used to convert and control the flow of electrical power. Power Electronics deals with the applications of solid state electronic devices in the control and conversion of electric power. Power Electronics can be described as an area where anything from a few watts to over several thousand watts are controlled by modern semiconductor control elements which consume only few micro watts to mill watts in most areas. Power Electronics embraces the studies of:- (a) Power:- It deals with both rotating and static equipment for the generation, transmission, distribution and utilization of vast quantities of electrical power. (b) Electronics:- It deals with the study of semiconductor devices and circuits for the processing of information at lower power levels. (c) Control:- In deals with the stability and response characteristics of closed loop system. Power Electronics deals with the use of electronics for control and conversion of large amount of electrical power. em ternal energy ves connecter erform the control Power Contral Analog Dig Electronics Devices Crouts Electronics Rotating Fig 1: Combinations of power electronics
