When measuring resistance with an ohmmeter, what should you ensure?

  1. Connect the power

  2. Disconnect the power

  3. Keep the circuit open

  4. Use a high range setting

The correct answer is: Disconnect the power

When measuring resistance with an ohmmeter, you should always ensure that the power is disconnected. This is because adding power to the circuit can change the resistance and affect the accuracy of the measurement. Additionally, keeping the circuit open (choice C) will not allow for a complete measurement and using a high range setting (choice D) can cause inaccurate readings.
