Question
An incomplete sentence about transistors is given below:
The emitter−..... junction is __ and the collector−..... junction is __. The appropriate words for the dotted empty positions are, respectively,
Options
'collector' and 'base'
'base' and 'emitter'
'collector' and 'emitter'
'base' and 'base'.
Solution
'base' and 'base'
In transistors, the emitter−base junction is forward biassed and the collector−base junction is reverse biassed. This is done to make majority carriers cross the emitter−base junction; this helps the electric current to flow through the transistor.
