Electrical Safety and Maintenance Quiz

Extension cords are not permitted to run across the floor of a workstation because:

• They can cause tripping hazards.

• They are too short.

• They are too expensive.

• They are not durable.

Circuit testers determine if:

• AC electricity is present.

• The circuit is complete.

• The circuit is broken.

• The circuit is grounded.

Improper grounding is most likely to result in:

• A shock from electrical devices.

• A short circuit.

• A power surge.

• A blown fuse.

The part of an electrical circuit that gives the operator control is the:

• Input device.

• Output device.

• Power source.

• Ground wire.

The meter shown is connected in the circuit so that it measures:

• Resistance, current, or voltage.

• Only resistance.

• Only current.

• Only voltage.

The following diagram is an example of OR logic. Identify OR logic circuit.

• A circuit with two inputs and one output where the output is true if at least one input is true.

• A circuit with two inputs and one output where the output is true only if both inputs are true.

• A circuit with one input and one output where the output is always true.

• A circuit with two inputs and one output where the output is true only if both inputs are false.

A multimeter is a multipurpose device that can measure:

• Voltage, current, and resistance.

• Only voltage.

• Only current.

• Only resistance.

The primary purpose of a switch is to:

• Energize and de-energize circuits.

• Measure voltage.

• Measure current.

• Measure resistance.

Devices called relays often serve as:

• The brains of an automated machine.

• The power source of a machine.

• The input device of a machine.

• The output device of a machine.

Reactive maintenance would be classified as:

• An unplanned downtime maintenance activity.

• A planned maintenance activity.

• A preventive maintenance activity.

• A scheduled maintenance activity.
