Question

For a tansistor working as common base amplifier, the emitter current is 7.2 mA. The current gain is 0.96. The collector current is –

• A. 0.96 × 7.2 mA
• B. $\frac{0.96}{0.72}$ mA
• C. 0.96 – 7.2 mA
• D. 7.2 A – 2 × 0.96 mA

Answer 1

Answer: (A)

0.96 × 7.2 mA

Answer 2

a = $\frac{i_{C}}{i_{E}}$

i_C = a i_E = 0.96×7.2 mA
