- While measuring resistance: Technician A uses an ohmmeter to measure resistance of a component before disconnecting it from the circuit. Technician B uses a voltmeter to measure voltage drop. A circuit with very low resistance will drop zero or very little voltage. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile 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 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_forward

Technician A Technician B Both A and B Neither A nor Barrow_forwardWhile testing variable resistors: Technician A says that while checking a rheostat with a voltmeter, the voltage should change smoothly with a change in the control. Technician B says that a potentiometer can be checked with a scope. 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_forwardWhile discussing solar sensors: Technician A says that a solar sensor is a photo diode that receives a 5-volt reference signal from the control module.
