VCC of a bipolar junction transistor is the DC voltage that is supplied to the collector of the transistor.
VCC is a very important voltage when biasing the transistor because it determines how much the AC signal can be amplified to in the transistor. If VCC is too low, the transistor will not have enough power and the amplified AC signal will come out clipped.
VCC normally does not have to be calculated in a transistor circuit, as it's normally just given. However, it is very important when calculating other values in a transistor such as IC, the current through the collector and Ie, the current through the emitter. VCC is also important for calculating the load line of the transistor and thusits Q-point.

VCC (Collector Voltage):
- VCC is the DC voltage applied to the collector terminal of a BJT.
- It plays a crucial role in biasing the transistor, determining the transistor's operating point and influencing the amplification of the AC signal.
-
IC (Collector Current):
- IC refers to the collector current, which is the current flowing through the collector terminal of the transistor.
- VCC is essential when calculating IC, as it affects the transistor's power and performance.
-
IE (Emitter Current):
- IE is the emitter current, representing the current flowing through the emitter terminal of the transistor.
- VCC is significant when calculating IE, as it contributes to the overall understanding of the transistor's behavior.
