  • Khi R3 = Khi R4
khi R2 >> R1
khi R2 = 0

Trăng si tơ hoạt động như Công Tắc Điện Tử . Công tắc đóng khi R2 = 0 . Công tắc mở khi R2 >> R1


  • Khi R2 >> R1

Trăng si tơ hoạt động như Khuếch Đại Điện Âm . Với Khuếch đại n R3 = (n=1) R4

Summary[edit]

  • Khi R2 >> R1 then
khi R3 = (n+1)R3

Transistor operates as Inverting amplifier

  • Khi R3 = Khi R4, then
khi R2 >> R1
Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "/mathoid/local/v1/":): {\displaystyle V_C = 1} khi R2 = 0

Transistor operates as a closed switch when R2 >> R1 as a opened switch when R2 = 0
