When a number of stages are connected in parallel, the overall gain is the product of the individual stage gains
A. True
B. False
Answer: Option B
Solution (By Examveda Team)
When amplifier stages are connected in parallel, the overall gain is not the product of the individual stage gains.Parallel connection means the input signal is applied to multiple amplifier stages simultaneously, and their outputs are combined.
In this case, the gain of each path remains the same and does not multiply. Instead, the currents or voltages at the output may add, depending on how the stages are combined.
Overall gain in parallel configuration is determined by other factors such as how the outputs are summed and whether any loading effects are present.
In contrast, when amplifier stages are connected in series (cascaded), the overall gain is the product of the individual gains.
Therefore, the statement is false for parallel connection.

This statement is false. It will be true if the stages are cascaded. Then the total gain will be the multiple of individual stages
the answer must be TRUE, because the overall gain must be multiplied by individual stage gains. But if given in dB, the overall gain will be the sum of all gains in dB.
