Electronic – BJT Base Collector short circuit

When BJT's collector and base are shorted, then what happens for the circuit or may I say the change of BJT's performance in the circuit as there Vbc is zero.

Is it work like normal BJT where there is Ic and Ib current ?

Or, It just work like a diode as there is only one biasing voltage difference between one pn junction and zero voltage difference ( so no foreword or rivers bias ) for other junction?

Best Answer

Connecting the base to the collector makes it act as a diode, and will drop ~0.7V-1V
