Semiconductors – NET/GATE/Electronics/PH mock test- 4

For the common base circuit shown in the figure, determine $I_c$ and $V_CB$. Assume the transistor to be silicon.

in a common base connection, the emitter current is 1mA. If the emitter circuit is open, the collector current is 50 μA. Find the total collector current. Given that α=0.92.
