Which type of electrical testing device measures resistance?

• A. Voltmeter
• B. Resistance Meter
• C. Megger Meter
• D. Frequency Meter

Answer: (C)

The correct answer is the Megger Meter, which is specifically designed to measure insulation resistance. This device applies a high voltage to the insulation of electrical devices to determine how effectively it resists electrical leakage and potential breakdown. By measuring resistance, the Megger Meter helps ensure that electrical installations are safe and effective by identifying any weaknesses in insulation that could lead to failures or hazards.

While other testing devices have different primary functions, such as measuring voltage or frequency, they do not focus primarily on assessing resistance. Understanding these distinctions is crucial for properly utilizing the right tool for electrical testing tasks.
