Question

the selector switch on an ohmmeter is set to the setting labeled mω. what must the value indicated be multiplied by to find the actual number of ohms being detected by the ohmmeter?
100,000
1000
1,000,000
100

Explanation:

The unit MΩ (megaohm) is a unit of electrical resistance. By definition, 1 megaohm ($1\ \text{M}\Omega$) is equal to $1,000,000$ ohms ($\Omega$). So, if the ohmmeter is set to the MΩ setting, the indicated value must be multiplied by $1,000,000$ to get the actual resistance in ohms.

Answer:

1,000,000 (corresponding to the option "1,000,000")
