In the given circuit the silicon transistor has β = 75 collector voltage VC = 9V. The ratio of RB and RC is ______.
-
- 45.1
- 105.1
- 90
- All of the above
Correct Option: B
IC = BIB
IC = 75 IB
IC + IB = 75 IB + IB = 76IB
| IC + IB = | ||
| RC |
| 76 IB = | ...(i) | |
| RC |
| IB = | = | ...(ii) | ||
| RB | RB |
Equation (i) / Equation (ii),
| = | = | × | |||||
| IB | 8.3 / RC | RC | 8.3 |
| = | = 105.1 | |||
| RC | 6 |
| = 105.13 | ||
| RC |
