Answer» Correct Option (d) ic is less than βdcib. Explanation: For transistor in common emitter mode the relation between collector current and collector emitter voltage is given by vce= vcc-ICRC cut off occurs when Ic= 0 Saturation It occurs when there is no longer a change in collector current for a change in base current Active Mode In this mode the following relation is valid ic =β Iβ Thus in saturation the collector current does not increase with base current |
