Why is the base region of a transistor kept thin and lightly doped?
1 Answer
Apoorva Arora
Base provides the proper junction for interconnection between emitter and collector. It is made thin and slightly doped so, the number of majority carriers is low. So less number of electron-hole recombination take place and whole current emitted from the emitter with a slight difference is passed to the collector.
Thanks and Regards

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
