100

This type of current flows in only one direction all the time.

What is Direct Current (DC)?

100

This is the placement of a lock on an energy-isolating device to prevent operation.

What it Lockout?

100

This document sets minimum safety rules for electrical installations and repairs.

What is the National Electrical Code (NEC)?

100

This is an arrangement consisting of a power source, conductors, and loads.

What is a Circuit?

100

This is the electromotive force or electrical pressure in a circuit.

What is Voltage?

200

This term refers to the flow of electrons through a circuit, measured in amperes.

What is Current?

200

This is the placement of a securely fastened tag to an energy-isolating device.

What is Tagout?

200

This must be done before removing lockout/tagout devices and re-energizing equipment.

What is notify employees and inspect the work area?

200

This is a part of a circuit that uses power and performs a function.

What is a Load?

200

This law relates voltage, current, and resistance: E=I×RE=I×R.

What is Ohm's Law?

300

This is the opposition to current flow in an electrical circuit, measured in ohms.

What is Resistance?

300

This is the first step in a proper LOTO procedure.

What is Prepare for shutdown?

300

This type of device shuts off a circuit when current flows along an unintended path.

What is a Ground Fault Circuit Interrupter (GFCI)?

300

Any substance that takes up space and has mass.

What is Matter?

300

This is the abbreviation for voltage in formulas.

What is E?

400

This person has the necessary knowledge and skills to operate electrical equipment.

Who is a Qualified Technician?

400

This device measures volts, amps, and ohms in a circuit.

What is a Multimeter?

400

This is the abbreviation for current in formulas.

What is I?

500

This type of current reverses direction at regular intervals.

What is Alternating Current (AC)?

500

This is the most thorough system for securing equipment during maintenance.

What is using both locks and tags simultaneously?

500

This is a required step to verify all hazardous energy is controlled before servicing.

What is Verify machine is safe (isolation verification)?

500

This is the electrical work being done in a circuit, measured in watts or volt-amps.

What is Power?

500

This is the abbreviation for resistance in formulas.
