Who is correct when discussing the tools used to measure resistance and voltage drop?

The assertion that both technicians are correct highlights the importance of understanding various tools employed for electrical diagnostics in automotive systems. When discussing the measurement of resistance and voltage drop, both concepts are integral to diagnosing electrical issues.

Technician A likely explained how a multimeter is utilized to measure resistance, which is essential for determining whether a circuit or component is functioning correctly. A multimeter can measure resistance in ohms, allowing the technician to verify if a component is open or shorted.

Technician B probably addressed the measurement of voltage drop, perhaps using the same multimeter or a specialized tool like a voltmeter. A voltage drop test is crucial for assessing the performance of electrical connections, wires, and components under load. It helps to reveal problems such as poor connections, excessive resistance, or failing components by showing how much voltage is lost along the circuit.

In this context, both technicians provide accurate information regarding the appropriate tools and their specific applications for measuring resistance and voltage drop, thereby reinforcing the importance of these diagnostic methods in automotive electrical troubleshooting.
