The voltage gain and current gain of a transistor amplifier in common emitter configuration are respectively 150 and 50 . If the resistance in the base circuit is 850 , then the resistance in the collector circuit is

Options

  1. A1700
  2. B2250
  3. C2550
  4. D3000

Correct answer

C. 2550

Step-by-step solution

For CE configuration of transistor, aligned & A_v=150, =50, R_B=850 & Voltage gain, A_v= ( R₀ R_I )= ( R_C R_B ) & 150=50 R_c 850 & R_c=3 850=2550 aligned
