From Figure 1, the Collector to Base Current when the emitter leg is open is the notation used for current on the specification sheets. For general purpose transistors the level of is low and it is mid power range. The magnitude of in higher levels is in the microampere range.

The circuit conditions related to is shown in Figure 2:

From Figure 2, the Collector to Emitter Current when the base leg is open is the notation used for current on the specification sheets. For general purpose transistors the level of is low and it is mid power range. The magnitude of in higher levels is in the microampere range.

From Figure 1 and 2, the current is occurred at emitter leg is open and the current is occurred at base leg is open. But, both these collector currents and are the notations used for.

Yes, they are typically close in magnitude since the emitter current is nearly equal to the collector current.
