※ 引述《DivineAngel (Skates)》之銘言： : Find IB，IE，and IC in Figure 4-56 αDC=0.98 IE = 1.3 / 1 = 1.3 mA IC = 1.3 * 0.98 = 1.274 mA IB = 1.3 - 1.274 = 0.026 mA : ↓↓↓圖4-56↓↓↓ : http://xs.to/xs.php?h=xs322&d=07494&f=4-56.JPG

: Determine the terminal voltages of each transistor with respect to ground : for each circuit in Figure 4-57. Also determine VCE，VBE，VCB. (a) VB = 10V VE = 9.3V VC = 20V VCE = 10.7V VBE = 0.7V VCB = 10V (b) VB = -4V VE = -3.3V VC = -12V VCE = -8.7V VBE = -0.7V VCB = -8V : ↓↓↓圖4-57↓↓↓ : http://xs.to/xs.php?h=xs122&d=07494&f=4-57.JPG
