A transistor has two p-n junctions. The batteries should be connected such that
both junctions are forward biased
both junctions are reverse biased
one junction is forward biased and the other is reverse biased
none of the above
Correct answer is C
Emitter-base junction is forward biased and base collector junction is reverse biased.
The number of doped regions in PIN diode is
1
2
3
1 or 2
Correct answer is B
A PIN diode has p and n doped regions separated by intrinsic layer.
In an n-p-n transistor, the majority carriers in the base are
electrons
holes
both holes and electrons
either holes or electrons
Correct answer is A
Emitter is n type and emits electrons which diffuse through the base.
