Question

In the following common emitter circuit, β = 100 and V CE = 7 V . If V BE is negligible, then the base current is, 0 . 01 mA, 0 . 04 mA, 0 . 02 mA, 0 . 03 mA

The figure below represents the common emitter circuit, Apply Kirchhoff law, - 15 + 2 I C + V C E = 0 - 15 + 2 I c + 7 = 0 I C = 4 mA The common emitter gain is, β = I C I B 100 = 4 × 10 - 3 I B I B = 0 . 04 mA
