Cut off condition and saturated condition of transistors
In the switch circuit, transistor sometimes be in the inactive state, where there is no any current flows through it. These conditions is called transistor's cut off condition.
Figure A shows the state of the transistor in a cut off condition
At other times when the transistor is in the fully active state, where there are only a relatively small potential difference between the emitter and collector terminals. These conditions is called transistor's saturated condition.
Figure B shows the state of the transistor in saturated condition.
