Question

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

• A. both $I_{C}, I_{E}$ increase initially
• B. both $I_{C}, I_{E}$ decrease but $I_{E}$ decreases
• C. initially $I_{C}$ increases but $I_{E}$ decreases
• D. initially $I_{C}$ decreases but $I_{E}$ increases

Answer 1

Answer: (A)

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