Exam 2: Basic Theoriesspecial Tools and Procedures

The figure below represents what type of circuit?

A scan tool allows a technician to determine load voltage drops.

What does a lab scope provide?

The insulation test function is being discussed. Technician A says that the test is performed with the circuit powered. Technician B says the meter displays the circuit's voltage. Who is correct?

Technician A says a voltmeter measures the electrical difference between two points of the circuit. Technician B says a voltmeter that is connected in parallel to the load device will indicate the voltage drop across the device. Who is correct?

What is an ohmmeter used for?

What will adding resistance to a series circuit cause?

An analog meter is often used to test computer-controlled circuits.

In a series circuit, total resistance will always be lower than any one resistance value.

What is a sine wave?

Define Ohm's law.

A digital multimeter is being used to measure current flow. The meter displays 97.5 mA. Technician A says this represents 9.75 amperes. Technician B says this represents 0.0975 amperes. Who is correct?

What is the total resistance in a circuit with three 10-ohm resistors wired in parallel.?

Connected to the ____ through diagnostic connectors, a scan tool can access diagnostic trouble codes (DTCs), run tests to check system operations, and monitor the activity of the system.

Each lamp in the circuit shown has 12 ohms of resistance. Will the three lamps put out the same amount of light? Why or why not?

Where can you find information concerning service procedures?

What do scan tools interface with on a vehicle?

What does a voltmeter measure?

Voltage will exist between any two points in a circuit unless the potential drops to zero.

The ____ is a contract between the customer and the shop to have specified service performed.
