Initially, both IC and IE increase.

Q. For tuned collector oscillator, using an $n - p - n$ transistor, from rise and fall (or built up) of $I_{C}, I_{E}$ current graphs. It can be concluded

both $I_{C}, I_{E}$ increase initially

both $I_{C}, I_{E}$ decrease but $I_{E}$ decreases

initially $I_{C}$ increases but $I_{E}$ decreases

initially $I_{C}$ decreases but $I_{E}$ increases

Initially, both $I_{C}$ and $I_{E}$ increase.

Q. For tuned collector oscillator, using an n−p−n transistor, from rise and fall (or built up) of IC​,IE​ current graphs. It can be concluded

both IC​,IE​ increase initially

both IC​,IE​ decrease but IE​ decreases

initially IC​ increases but IE​ decreases

initially IC​ decreases but IE​ increases
