Question
Download Solution PDFIn a silicon transistor, a change of 8 mA in emitter current produces a change of 7.8 mA in the collector current. What change in base current is necessary to produce an equivalent change in collector current?
Answer (Detailed Solution Below)

Download Solution PDFConcept:
In a transistor, emitter current is calculated as
IE = IC + IB
Also, ∆IE = ∆IC + ∆IB
Where,
∆IE = Change in emitter current
∆IC = Change in collector current
∆IB = Change in base current
Calculation:
Given-
∆IE = 8 mA, ∆IC = 7.8 mA
∴ ∆IB = 8 - 7.8 = 0.2 mA
∆IB = 0.2 mA
