railway RRB JE (CBT I + CBT II) Mock Test 2024 Electronic Devices Bipolar Junction Transistor Currents in a BJT
Which of the following represents the correct relationship between collector to emitter cut-off current (ICEO) of a transistor and collector to base cut-off current (ICBO)?
(Assume: 'x' is the CB current gain of the transistor)
1
IECO = ICBO
2
IECO = x ⋅ ICBO
3
IECO = ICBO/(1 - x)
4
IECO = ICBO/ (1 + x)
