Final answer:
The current gain of the given circuit is 4.71.
Step-by-step explanation:
The current gain of a circuit can be calculated using the formula:
Current Gain (β) = R2 / R1
In this circuit, the values of R1 and R2 are given as 3.4 and 16.0 respectively. Plugging these values into the formula, we get:
Current Gain (β) = 16.0 / 3.4 = 4.71
Therefore, the current gain of the circuit is approximately 4.71.
