Analyze the results of a practical experiment involving voltage measurements and transformer characteristics, filling in missing table values and drawing conclusions.

Here's an analysis of the provided worksheet:

Sub-task 3 (Table 1):
The "Winding (PRIM)" and "Winding (SEC)" rows are empty. These typically refer to the number of turns or specific winding configurations. Without additional information or context from the practical instructions, these values cannot be determined or filled.
The provided values are:

• Primary voltage: $220 \text{ V } 50 \text{ Hz}$
• Secondary voltage: $9.0 \text{ V } 1 \text{ A}$

Sub-task 4 (Table 2):
This table is already filled with the measured values:

• $V_2$: $11.29 \text{ V}$
• $V_{OUTPUT}$: $4.72 \text{ mV}$

Sub-task 5 (Table 3):
This table is completely empty. As these are "Measured values," they cannot be filled without performing the experiment or having access to the experimental results for Sub-task 5.

Sub-task 6 (Table 4):
This table is already filled with the measured values:

• $V_2$: $11.34 \text{ V}$
• $V_{OUTPUT}$: $101.5 \text{ mV}$

Sub-task 7 (Conclusion):
Based on the available data from Sub-tasks 3, 4, and 6:
The practical involves analyzing voltage characteristics. Sub-task 3 describes a power source or transformer providing a step-down from $220 \text{ V}$ to $9.0 \text{ V}$. In Sub-task 4, an input voltage $V_2$ of $11.29 \text{ V}$ resulted in an output voltage $V_{OUTPUT}$ of $4.72 \text{ mV}$. In contrast, Sub-task 6, with a very similar input voltage $V_2$ of $11.34 \text{ V}$, yielded a significantly higher output voltage of $101.5 \text{ mV}$. This substantial increase in $V_{OUTPUT}$ for a nearly identical $V_2$ suggests that the circuit configuration, gain settings, or load conditions were altered between Sub-task 4 and Sub-task 6, leading to a different voltage transfer characteristic.
