Vedclass · Answer

(A) The correct option is $A$. In a transistor,the emitter-base junction is forward-biased and the collector-base junction is reverse-biased. If the forward bias is made too large,a very high number of majority charge carriers will be injected from the emitter into the base. These carriers then move to the collector with high velocity. This results in a high current flow,which leads to excessive heating of the transistor,potentially causing permanent damage to the device.

In a transistor,the forward bias is always kept smaller than the reverse bias. The correct reason is:
