The correct Answer is:
To solve the question regarding the frequency of AC mains in India, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Question**: The question asks for the frequency of the alternating current (AC) mains supply in India. 2. **Identify the Standard Frequency**: In India, the standard frequency for AC mains supply is commonly known. It is important to recall this standard. 3. **Recall the Value**: The frequency of AC mains in India is 50 Hertz (Hz). This means that the current alternates 50 times per second. 4. **Convert to Other Units (if necessary)**: It is also useful to note that Hertz (Hz) is equivalent to cycles per second (CPS). Therefore, 50 Hz can also be expressed as 50 cycles per second. 5. **Conclude the Answer**: Based on the information, we can conclude that the frequency of AC mains in India is 50 Hz. ### Final Answer: The frequency of AC mains in India is **50 Hz**. ---
