Question

The current gain in Common Base configuration (α) is
A. Ratio of Base Current to Emitter Current (IB/IE)
B. Ratio of Collector Current to Emitter Current (IC/IE)
C. Ratio of Collector Current to Base Current (IC/IB)
D. None
Q.16 JFET is considered as a voltage​

Answer 1

α and β are the parameters for a transistor which defines the current gain in a transistor. α is defined as the ratio of the collector current to the emitter current. β is defined as the current gain which is given by the ratio of the collector current to the base current.

B. Ratio of collector current Emitter Current
