One ohm is equal to

Options

A. `10^(6)Momega`
B. `10^(9) M omega`
C. `10^(-6) M Omega`
D. none of these

Explanation

To solve the question "One ohm is equal to", we will convert ohms to mega ohms and find the correct answer among the given options.

### Step-by-Step Solution:

1. **Understanding Mega Ohm**:
- 1 Mega Ohm (MΩ) is defined as \(10^6\) ohms.
- This means that 1 Mega Ohm is equal to 1,000,000 ohms.

2. **Setting Up the Conversion**:
- We want to express 1 ohm in terms of Mega Ohms.
- We can use the relationship we just established:
\[ 1 \text{ MΩ} = 10^6 \text{ ohms} \]

3. **Expressing 1 Ohm in Mega Ohms**:
- To find out how many Mega Ohms are in 1 ohm, we can set up the equation:
\[ 1 \text{ ohm} = \frac{1 \text{ MΩ}}{10^6} \]
- This simplifies to:
\[ 1 \text{ ohm} = 10^{-6} \text{ MΩ} \]

4. **Conclusion**:
- Therefore, we conclude that:
\[ 1 \text{ ohm} = 10^{-6} \text{ Mega Ohm} \]
- This corresponds to option 3 in the question.

### Final Answer:
1 Ohm is equal to \(10^{-6}\) Mega Ohm.
