The emitter current in a junction transistor with normal

Home » Physical Electronics Devices and ICs » Physical electronics devices and ics miscellaneous » Question

The emitter current in a junction transistor with normal bias—

1. May be greatly increased by a small change in collector bias
2. Is equal to the sum of the base current and collector current
3. Is approximately equal to the base current
4. Is designated as I_CO

Correct Option: B

In normal bias I_E = I_B + I_C
Hence alternative (B) is the correct answer.
