True or False: An analog meter can measure resistance without shorting the leads first.

True or False: An analog meter can measure resistance without shorting the leads first.

• A. True
• B. False
• C. Depends on the meter
• D. Only if the meter is calibrated

Answer: (B)

An analog meter cannot measure resistance without shorting the leads first because the process of measuring resistance involves sending a small current through the resistor being tested. When the leads are shorted, it allows the meter to zero out any resistance that may be present in the leads themselves, ensuring an accurate measurement. If the leads are not shorted, the meter may not provide a correct reading, as it would include any additional resistance from the leads, making the measurement inaccurate. This is a key principle in using analog meters properly to ensure reliable results when measuring resistance.
