Voltage in the secondary coil of a transfomer does not depend upon

Options

A. Frequency of the source
B. Voltage in the primary coil
C. Ratio of number of turns in the two coils
D. Both (2) and (3)

Answer

To solve the question regarding the dependency of voltage in the secondary coil of a transformer, we can follow these steps:

### Step-by-Step Solution

1. **Understanding the Transformer Equation**:
The relationship between the primary voltage (V_p) and the secondary voltage (V_s) in a transformer is given by the formula:
\[ \frac{V_p}{V_s} = \frac{N_p}{N_s} \]
where \(N_p\) is the number of turns in the primary coil and \(N_s\) is the number of turns in the secondary coil.

2. **Identifying Dependencies**:
From the equation, we can see that:
- The secondary voltage \(V_s\) is directly related to the primary voltage \(V_p\).
- The secondary voltage \(V_s\) is also dependent on the ratio of the number of turns in the primary and secondary coils (\(N_p\) and \(N_s\)).

3. **Determining What It Does Not Depend On**:
The equation does not include any term for frequency. This indicates that the voltage in the secondary coil does not depend on the frequency of the alternating current (AC) source.

4. **Conclusion**:
Thus, the voltage in the secondary coil of a transformer does not depend on the frequency of the source.

### Final Answer:
The voltage in the secondary coil of a transformer does not depend upon the frequency of the source.
