1.a)Find the change in currents due to change of voltage by (a)5mv, (b) -10mv, (c) 15mv using small signal model and exponentialmodel of diode with n= 1 and biased at 2mA.
b)A step up transformer has the turn ratio of2:5, find the secondary voltage of transformer ifprimary voltage given is 240 Vac.
2.What surveying observations does a contractor need to lay a 36 inch diameter pipe?
3.What is the conversion rate for parts per million by volume (ppmv)conversion. How is this converted into atm, Pa, and torr?
