Emitter Resistor Open Circuit Tutorial

There can be no base or collector current.

Since the current through R1 is less than normal, there will be a lower voltage drop across it and the base voltage will be higher than normal.

Since there is no current through R3 there will be no voltage dropped across it. The voltage will be the same at both ends, and the collector will be at the supply voltage.

We would expect there to be no voltage across R4, but the meter connects the emitter to zero volts and some current flows through the meter.

The voltage indicated would depend upon the type of meter.
