Quick NPN transistor question

Hi,
If the voltages of the Base and Collector are the same whilst the voltage of Emitter is equal to the supply. Is this a sign that the transistor is shorted between the base and collector?

Many thanks
Matt

Are you sure you're talking about an NPN transistor?

Normally in an NPN circuit, the emitter is closest to ground!

If the emitter is measuring the same as the supply voltage, then the load WAS between the emitter and ground, but it is now open, and all three (E, B, C) would measure about the same voltage.
