In a transistor beta= 45, the change in the v voltage across 5 kOmegaresistor which is connected in collector M circuit is 5V. Find the change in base current. |

Answer» SOLUTION :Change in the collector CURRENT `Delta I_C = Delta V //R_L` But `BETA =( DeltaI_C )/(Delta I_B) ` ` DeltaI_B= (Delta I_C ) /( beta) = (10^(-3))/(45)= 0.022 mA .` Change in BASE current `( Delta I_B ) = 0.022mA` |
