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,

विकल्प

• 'collector' and 'base'

•  'base' and 'emitter'

•  'collector' and 'emitter'

• 'base' and 'base'.

Answer 1

 '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.
