The current amplification factor and the collector current in a CE transistor circuit are 100 and 2.2 ~mA respectively. Then the base current is

Options

  1. A0.22 A
  2. B22 A
  3. C220 A
  4. D2.2 A

Correct answer

B. 22 A

Step-by-step solution

Current amplification favor, =100 Collector around, I_c=2.2 ~mA Base current, I _ B Using the relation, aligned & = I_C I_B & I_B= I_C = 2.2 10⁻³ 100 =2.2 10⁻⁵ & I_ =22 A aligned
