Hi,
Am trying to learn a simple circuit simulation with Pspice. The circuit is attached. All the base, collector and emitter resistors are 1K. And supplies are 5V. With this i expect the base current to be 42 microamp. But somehow Pspice seems to show 1.19 mA. Am i right in my calculation or there is something i need to do with the Pspice ?
The transistor i use is Q2N3416. Somebody kindly help me asap.
Exactly, how does I(R3) turn out to be 1.19 mA ? Cause if we apply KVL on the input side and having Beta=100(I hope am right here), I(R3) should be 42 microAmp.

Thank you eric for trying to help me out with this! Input impedance is 1k . The gain i.e Beta is 100 what i suppose it is.
So, with: 5 -IbRb - 0.7 - (Beta = 100)IbRe = 0 yields me Ib = 42 microAmp.

Hi eric, thanks for making me realize that i have put the transistor in the saturation. However i still have doubts: My class has started with transistor only a day back, so i dont know if i have come across the saturation conditions yet.
My doubt is : At saturation Ic should be just Vcc/Rc . So should Ie be. i.e Ie = Ic. but at according to the equation at the input Ib doesnt equal to 1.19 mA as suggested by Pspice.
