### Static electricity is best described as:

• A.

An electrical charge at rest

• B.

Charge induction

• C.

Excessive valence electrons

• D.

Electrostatic discharge

A. An electrical charge at rest
Explanation
Static electricity is best described as an electrical charge at rest. This means that the electrical charge is not flowing or moving, but rather it is stationary. Static electricity occurs when there is an imbalance of electrons on an object, causing it to become positively or negatively charged. This charge remains in place until it is discharged or neutralized.

Rate this question:

• 5.

### A conductor will:

• A.

Allow the flow of electrical current

• B.

Prevent the risk of shock

• C.

Prevent a wire from shorting to another wire

• D.

Resist the flow of electrical current

A. Allow the flow of electrical current
Explanation
A conductor is a material that allows the flow of electrical current through it. It has free electrons that can easily move and carry the electric charge. Unlike insulators, conductors have low resistance and do not impede the flow of current. Therefore, the correct answer is that a conductor allows the flow of electrical current.

Rate this question:

### Insulators:

• A.

Conduct electricity

• B.

Are grounding devices

• C.

Resist the flow of electricity

• D.

Fall somewhere between conductors and static dissipating materials

C. Resist the flow of electricity
Explanation
Insulators are materials that do not allow the flow of electricity easily. They have high electrical resistance, which means they resist the flow of electric current. Unlike conductors, which allow electricity to pass through them easily, insulators prevent the flow of electrons. This property makes insulators useful for protecting against electric shocks and preventing unwanted electrical currents. Therefore, the statement "resist the flow of electricity" accurately describes the behavior of insulators.
