What will be the total voltage amplification factor when three amplifiers having voltage gain of 3 are connected in series

Explanation

To find the total voltage amplification factor when three amplifiers, each with a voltage gain of 3, are connected in series, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Voltage Gain**: The voltage gain (A) of an amplifier is defined as the ratio of output voltage (Vout) to input voltage (Vin). For a single amplifier, this is expressed as:
\[ A = \frac{V_{out}}{V_{in}} \]
