Select the correct resistance measurement when the meter switch is in the "20M" position.

When the meter switch is in the "20M" position, the reading from the meter corresponds to a range of resistance measurements that can be expressed in different units. In this case, "20M" refers to a maximum reading capability of 20 megohms (MOhms), where 1 MOhm is equal to 1,000,000 ohms.

The resistance values provided can be converted as follows:

• 0.22 MOhms is equivalent to 220,000 ohms.

• 220K ohms is another way of expressing 220,000 ohms, since 1 KOhm equals 1,000 ohms.

• Consequently, 220,000 ohms directly reflects the numeric value given.

Thus, all three values—0.22 MOhms, 220K ohms, and 220,000 ohms—represent the same resistance measurement but in different units. Therefore, the selection of "All of the above" is correct since each option accurately describes the same resistance amount in various standard notations. This reflects an understanding of the relationship between the different units of resistance measurement.
