Simple question about KVL Equation in a BJT Circuit

• Engineering

Homework Statement

I am trying to find the KVL equation for this BJT in order to find Ib.

The Attempt at a Solution

My current equation looks like this.
Vcc - IcRc - IbRb - Vbe = 0

I am not entirely sure if this is correct.

1. Is the drop across Rc really just IcRc? (Hint: you're close, but no cigars).
2. More importantly, what is the relationship between Ib and Ic for a BJT?

The base current and collector current equals to the emitter current.

So, the drop across the Rc is actually IeRc?

Yes. Add the IbRc term to your original equation, don't use Ie.

Now for part 2?
