Chapter 22

5. An electrical circuit with a gap or break in continuity so that current cannot flow.
6. An electrical instrument used to measure the amount of resistance in a given unit or circuit.
7. Troubleshooting process that uses a logical sequence of steps to find the source of an electrical problem.
8. A description of a perfect electrical path between two test points.
10. A chemical for cleaning deposits from contacts, switches, and other components.
12. System malfunction that occurs infrequently, usually when certain conditions are met, such as temperature, humidity, vehicle operation, or in response to tests performed by a computer.
13. the amount voltage decreases as current flows through a component or part of a circuit.
14. used to measure voltage (electrical pressure) in a given circuit.

1. A description of a circuit path that is not complete; current is blocked through the tested circuit or component.
2. Short piece of insulated wire used to bypass electrical connections or devices to test operation.
3. A solvent used to clean oil and grease from components before soldering.
4. Solution used to find intermittent electrical problems by lowering the temperature of a component instantly.
9. An instrument used to measure the flow of electric current in a circuit in amperes. It is normally connected in series in a circuit.
11. The feature of a digital multimeter that automatically changes to the correct range. All that has to be set on the meter is the knob for volts, amps, or ohms.
