In a silicon transistor, a change of 8.86 mA in the emitter current produces a change of 6.254 mA in the collector current. What change in the base current is necessary to produce an equivalent change in the collector current?
Correct answer: C. 2.606 mA
- A. 15.114 mA
- B. 10.252 mA
- C. 2.606 mA
- D. 5.12 mA
Explanation
ΔIE = ΔIB + ΔIC. Thus, ΔIB = ΔE - ΔIC = 8.86 - 6.254 = 2.606 mA.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
