Which tool would be best for measuring electrical current?

A multimeter is the best tool for measuring electrical current because it is specifically designed to measure various electrical quantities, including voltage, resistance, and current. When used in current measurement mode, a multimeter can provide accurate readings of current flowing through a circuit, typically in amperes. This versatility makes it an essential tool for electricians and apprentices alike.

In comparison, a voltage tester primarily measures voltage levels without providing any information about the current. Its function is limited to checking whether a circuit is energized or not. A wire stripper is a tool used for removing insulation from electrical wires, which has no measuring capability. An ohmmeter is designed to measure resistance in a circuit and cannot measure current directly. Therefore, the multimeter stands out as the comprehensive option for measuring electrical current effectively.
