Q1: For the above circuit, given that R=4 Ohms and the current source Is=19 Amps, determine the current I1 in Amps.Be sure to round your answer to the nearest single digit decimal place. For example, if your answer is 10.5333 Amps, then enter 10.5See Answer
Q2: Q1) Doping is introduction of impurities into the intrinsic semiconductor for the purpose of modulating electrical, optical and structural properties. Doping is important because it greatly conductivity of semiconductor and also the hole electron concentration. Three materials which can use p type doping is Boron,Aluminium, Indium. The common characteristic of these elements is that they have one electron deficiency in valence shell.See Answer
