**Experimental Setup and Analysis**

In the experiment, you repeated measurements 13 times for a resistor. After data processing, you determined that the standard deviation of the measurements is 4.3 Ω. What is the standard error of the mean in units of Ω?

**Explanation:**

To find the standard error of the mean (SEM), use the formula:
\[ \text{SEM} = \frac{\sigma}{\sqrt{n}} \]
where:
- \( \sigma \) is the standard deviation of the measurements.
- \( n \) is the number of measurements.

Given:
- \( \sigma = 4.3 \, \Omega \)
- \( n = 13 \)

Insert the values into the formula to calculate the SEM.
