Relate `I_(E ),I_(B) and I_(C)` for a transistor.

Text Solution

Verified by Experts

`" " I_(E ) = I_(B) + I_(C) `
where, `" " I_(B) `- Base current , `I_(C )` - Collector current, `I_(E)` - Emitter current
and `" " I_(E ) = I_(h) + I_(e)`
where, `" "I_(h)` - hole current
and `" " I_(e )` -n electron current .
