In a Bipolar Junction Transistor (BJT), the current gain β is defined as the ratio of change in collector current to change in base current for constant collector voltage in collector-emiitter configuration i.e., β = (Δ Ic/Δ IB)

Q. In a Bipolar Junction Transistor $(B J T)$ , the current gain $β$ is defined is

the ratio of change in collector current to the change in emitter current for a constant collector voltage in the common base configuration

the ratio of change in emitter current to the change in base current for constant emitter voltage in common emitter configuration

the ratio of change in collector current to the change in base current for constant collector voltage in collector emitter configuration

the ratio of change in base current to the change in collector current for constant collector voltage in collector emitter configuration

In a Bipolar Junction Transistor $(B J T)$ , the current gain $β$ is defined as the ratio of change in collector current to change in base current for constant collector voltage in collector-emiitter configuration
i.e., $β = \frac{Δ I _{c}}{Δ I _{B}}$
