Which type of measurement is primarily done using a clamp on meter?

• A. Voltage
• B. Resistance
• C. Current
• D. Capacitance

Answer: (C)

A clamp-on meter is specifically designed for measuring current without needing to make direct contact with the electrical circuit. This is accomplished by using a sensor that can detect the magnetic field around a conductor when it passes through the clamp. This approach allows for safe and convenient measurement of current, particularly in situations where it may not be feasible or safe to break the circuit to insert a traditional current meter.

While other types of electrical measurements can be performed using different tools, such as a multimeter for voltage, resistance, and capacitance, these typically require a direct connection to the circuit or component being tested. In contrast, a clamp-on meter simplifies the process and enhances safety, making it the preferred choice for current measurements in many situations.
