1.

Discrete transistors T1 and T2 having maximum collector current rating of 0.75A are connected in parallel as shown in the figure. This combination is treated as a single transistor to carry a single current of 1A, when biased with a self bias circuit. When the circuit is switched ON, T1 had draws 0.55A and T2 draws 0.45A. If the supply is kept ON continuously, it is very likely that_________

A. both T1 and T2 get damaged
B. both T1 and T2 will be safe
C. only T1 gets damaged
D. only T2 gets damaged
Answer» D. only T2 gets damaged
