A. sketch a small-signal model of the circuit in your pre-lab, replacing the transistor with its small-signal model (use the t-model and ignore r o ) . label the base of the transistor as vin j. e., the small-signal voltage at the input. what are the values of g m and ? r e what is the ratio of 172 pan you annrovimata it?

What precautions should you take to prevent injuries when dealing with heavy loads?

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

Acarnot refrigerator operates in a room in which the temperature is 21°c and of power when operating. if the food compartment of the refrigerator is consumes 3 kw to be maintained at 2°c, determine (a) the coefficient of performance of the cycle and (b) the rate of heat removal from the food compartment. refrigerator cycle that has a higher coefficient of performance than that of the discussed (e) is it possible to develop a carn ot refrigerator, operating between the same temperature limits? explain
