Question

For a transistor, the current ratio 'β'dc is defined as the ratio of (A) collector current to emitter current (B) collector current to base current (C) base current to collector current (D) emitter current to collector current

The current amplification factor of a transistor for direct current (DC) is the ratio of collector current

(I_{C})

to the base current

(I_{B})

in common emitter configuration i.e.,

B_{D C} = \frac{I _{C}}{I _{B}}

However, the ratio of collector current to the emitter current gives the value of current amplification factor in common base configuration, i.e.,

α_{D C} = \frac{I _{C}}{I _{E}}
