What is the proper action before measuring current in a circuit?

Explanation:
Before measuring current, ensure the circuit is de-energized. Turning off the power protects you and the equipment from shocks, arcs, and meter damage. To measure current, you typically place the ammeter in series with the load so all current flows through the meter; a clamp-on meter can measure current around a conductor without breaking the circuit, but power status should be verified first. Ignoring power status or turning the power on creates obvious safety risks, and using another device wouldn’t address the need to safely measure current.
