Answer:
Explanation:
A bipolar junction transistor also known as the bipolar transistor or BJT is a transistor using both the electron and the hole charge carriers. In contrast, others such as the unipolar transistors, such as field-effect transistors, only use one kind of charge carrier. For the operation, BJTs use two junctions between two semiconductor types, n-type and p-type. Here, the current is also produced by both types of Charge Carriers, ie electrons and holes, hence the name is bipolar.
Collector current = Base current/Value
C = 30/100
C = .3
Thus the collector current will be 3 MA
