WebOct 29, 2015 · To fully turn on the BJT , Vbe must be greater than 0.7 but when I apply voltage divider rule , isn't R6/(R6+R5) * 12 v = 1.091V. Isn't this amount more than 0.7V which should turn on the BJT but it doesn't as shown in the multisim simulation. I am still learning how BJT work so I simulate this in Multisim.
