18.
Discrete transistors T1 and T2 having maximum collector current rating of 0.75 amp are connected in parallel as shown in the figure, this combination is treated as a single transistor to carry a total current of 1 ampere, when biased with self bias circuit. When the circuit is switched on, T1 draws 0.55 amps and T2 draws 0.45 amps. If the supply is kept on continuously, ultimately it is very likely that


Answer: Option
Explanation:
T1 draws 0.55 A and T2 draws 0.45 A, T1 will get more heated and correct increase. Ultimately, I1 = 1A and I2 = 0.
