bipolar npn transistor

What is the base-collector voltage in a NPN transistor?
What is the base-collector voltage in relation to the base-emitter voltage and receiver-emitter voltage in an NPN bipolar junction transistor?
I'm assuming that the transistor is in the linear region. (Other regions are saturated and cut). The VBE is 0.6 or 0.7 volts, fairly constant. Collector voltage (VCE) is arbitrary and is determined by the bias network, as is the CCV. A typical application, as a linear amplifier can have the supply to 12 volts, the collector to 7 volts, and emitter to 2 volts, and IC = 10 mA. This will gives stress on the transistor VBE = 0.6, VCE = 5V, VCB = 4.4 volts.
