BJT Biasing - Simple easy 1 minute answer

Homework Statement

Find IB, IC, IE, VCE, VBC, and VEB for the NPN transistor in the circuit below for β = 50, 150, 500. Let VCC = 10 V, R1 = 100 KΩ, R2 = 400 KΩ, RC=2 KΩ, and RE = 0 Ω. Assume VBE = 0.7V.

Homework Equations

V = iR
IE = Ib + Ic

The Attempt at a Solution

My question is that if RE = 0 ohms, then is Ie automatically 0 amps?

But the how does Ie = Ib + Ic apply? Because I got 92.25uA for Ib and 4.56mA for Ic?

Help! :]

Forgot to put the figure :]

No. A piece of connecting wire from emitter to ground = 0 Ω

No. A piece of connecting wire from emitter to ground = 0 Ω

Awwww!

:[ So Ie = Ib + Ic is correct?

I would use this to calculate Ie?

Yes.

It is involved in the calculations.
