DISCUSSIONS: 1) What is the Darlington Pair? and what is the main features of it?. 2) From your results, Compare the current gain and input impedance of Darlington Pair circuit with respect to single transistor. 3) What are the relationship between the state of the relay with respect to photoresistance, explain it by your results (Vn. Ve and Ic). 4) Explain the effect of changing the relay connection to emitter and collector in the values of voltage of Ci and time delay. Explain the operation of the two circuits.
