The amp clamp can be used on which type of circuits?

• A. Any circuit
• B. Only DC circuits
• C. Only AC circuits
• D. Only high-current circuits

Answer: (A)

An amp clamp measures current without opening the circuit by using the magnetic field around a conductor. You place the clamp around a single wire, and the device senses the current flowing through that wire and shows it on the display. Because the reading comes from the amount of current in that conductor rather than the circuit’s voltage type, it can be used on any circuit as long as you pass only one conductor through the jaws and stay within the clamp’s rated range. If you clamp around both the hot and neutral together, their fields cancel and you’ll get no reading, so be sure to isolate a single conductor. Some clamps are designed for AC only or DC only, but many modern models read both types. In short, the amp clamp works across circuit types because it measures current directly in a single conductor without altering the circuit.
