Consider the diode terminal I-V relationship stemming from the physics of the underlying pn junction: where I0 is the saturation current and VT = kT/q is the thermal voltage. a. Sketch the I-V characteristic for I0 = 10 fA and VT = 25.9 mV by plotting 10 points and drawing a smooth curve through them. b. Label the part of the characteristic that corresponds to: i. forward bias ii. reverse bias

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
