The National Electrical Code (NEC ) only defines electrical circuits that are required to be grounded.

The grounded conductor is defined as one that is intentionally grounded or connected to earth.

The unit of electrical resistance in the circuit is known as the ampere.

A bonding ____ is a conductor, made of copper or aluminum, used to ensure electrical conductivity between metal parts that must be electrically connected. A) electrode B) shunter C) jumper D) transformer

Which of the following formulas represents Ohm's law? A) E (volts) = I (amperes) ÷ R (ohms) B) E (volts) = I (amperes) - R (ohms) C) E (volts) = I (amperes) + R (ohms) D) E (volts) = I (amperes) × R (ohms)

The unit of electrical current is the ____. A) ampere B) volt C) ohm D) watt

A ____ circuit is one in which there is more than one path for current to flow in. A) neutral B) parallel C) series D) resistive

A grounding ____ is a conducting object through which a direct connection to earth is established. A) conductor B) jumper C) electrode D) generator

Soil resistivity is determined largely by its content of ____________________, which consist of moisture, minerals, and dissolved salts.

In a(n) ____________________ circuit, there is only one path for current to flow.
