Correct option is B
he current gain of a Darlington amplifier is the product of the current gains of the two transistors used in the configuration. If the current gains of the two transistors are
β₁ and
β₂, then the total current gain of the Darlington pair is:
Total Current Gain=β1×β2
· A Darlington amplifier consists of two transistors connected in such a way that the emitter of the first transistor is connected to the base of the second transistor.
· The current gain of the first transistor (β₁) multiplies with the current gain of the second transistor (β₂), resulting in a very high overall current gain (β₁ * β₂).
· This configuration is commonly used in applications requiring high current gain, such as in power amplifiers or driver circuits.
