- While measuring the resistance of a wire with an ohmmeter: Technician A says that if low resistance is shown on the meter, the wire is shorted. Technician B says that if no resistance is measured, the wire is shorted. Who is correct? Technician A Technician B Both A and B d. Neither A nor Barrow_forwardWhile diagnosing the location of a wire-to-wire short: Technician A checks the wiring of the affected circuits for signs of burned insulation and melted conductors. Technician B checks common connectors shared by the two affected circuits. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTrue or False? A zero reading on an ohmmeter means the circuit or component is open.arrow_forward
- While discussing copper wire: Technician A says that if the length of wire is doubled, the resistance between the wire ends is doubled. Technician B says that if the diameter of a wire is doubled, the resistance between the wire ends is doubled. Who is correct?
