- 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 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? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile discussing current flow: Technician A says that current results from electrons being attracted to protons. Technician B says that for practical purposes, it is best to remember that current flows from a point of higher potential to a point of lower potential. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- While checking an A/C compressor clutch coil spikesuppressing diode with an ohmmeter, the meter shows infinite resistance when the diode is measured in both directions: Technician A says that the diode is open. Technician B says that all diodes should behave this way until a specified voltage is applied to them. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile checking an A/C compressor clutch coil clamping diode with a DMM, the meter shows infinite resistance when the diode is measured in both directions: Technician A says that the diode is open. Technician B says that all diodes should behave this way until a specified voltage is applied to them. Who is correct? a. Technician A b. Technician B c. Both A and B d. Neither A nor Barrow_forwardTechnician A says that the waveform produced by an AC generator after rectification is called a sine wave. Technician B says that the waveform produced by the AC generator after the output moves through the diodes is a straight line because it is a constant DC voltage. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- True or False?

A. Thermistor B. Thermocouple C. Diaphragm D. Bimetalarrow_forwardWhile discussing voltage Technician A says that voltage is the force developed by the attraction of the electrons to protons. Technician B says that the force developed by the attraction of electrons to protons is called electromotive force and it is measured in volts. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- While discussing the results of a load test: Technician A says that if a battery fails a load test but the voltage rises above 12.4 volts when the load is removed, the battery should be replaced. Technician B says that if a battery fails a load test but the voltage rises above 12.4 volts when the load is removed, the battery is able to hold a charge. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTechnician A says that when a diode is placed in a circuit with the positive side of the circuit connected to the positive side of the diode and the negative side of the circuit connected to the negative side if the diode, the diode is said to have reverse bias. Technician B says that the diodes P material is repelled by the positive charge of the circuit and is pushed toward the N material and that the N material is pushed toward the P. Who is correct? Technician A Both A and B Technician B Neither A nor Barrow_forwardWhile discussing electrical grounds: Technician A says that a component may be grounded through its mounting to a major metal part. Technician B says that some components must be grounded by connecting its positive terminal to a metal section of the frame. Who is correct?
