Final answer:
A CC transistor circuit is also known as a Common-Collector circuit, which serves as an electric valve to control the current within the circuit. It is characterized by high input impedance and low output impedance, making it suitable for impedance matching applications.
Step-by-step explanation:
A CC transistor circuit is commonly referred to as a Common-Collector circuit. This configuration is used in applications that require impedance matching since it provides a high input impedance and a low output impedance. The terminology comes from the fact that in this arrangement, the collector is common to both the input and output of the circuit.
In the context of a junction transistor, the device has three parts: an n-type semiconductor (emitter), a p-type semiconductor (base), and another n-type semiconductor (collector).
When a voltage is applied to the base, it allows control of the current flowing from the emitter to the collector, effectively acting as an electric valve to control the current in a circuit. The base current (IB) is used to control the larger collector current (IC), demonstrating the current gain property of transistors.
To calculate the collector current, given the base current and the current gain, you would multiply the base current by the current gain.
For instance, if the base current is 4.4 A and the current gain is 1126, the collector current would be 4.4 A * 1126, which results in a collector current of 4954.4 A (assuming the provided base current should be in microamps or milliamps since amperes seem too high for typical transistor operation).
