While working on a school project, Mia needed to measure the current flowing through a wire without interrupting the circuit. She wondered which instrument would allow her to do this without making any connection in the wire being measured. The instrument used to measure current without actually making any connection in the wire being measured is the ....

• voltmeter

• instrument current transformer

• clamp meter

• megger
