- I am using voltage divider to find base voltage of transistor. I am getting two different results in two different circuits.
Hello,
I am trying to find base voltage. In attached picture (using Multisim) there are two separate circuits. Here is how I am doing the voltage divider:
Circuit on right:
Vb = (Vcc - .7)*R6/(R6 + R5) = 3.2V which matches Multisim result. No problem here.
Circuit on left:
Vb = (Vcc - .7)*R1/(R1 + R2) = 1.99V. Multisim giving result = 1.5V. My question is why ?
I checked with another simulator, and got same results as Multisim.
Am I doing something wrong ?
Thanks for any help.
