Electric Charges

The total electric charge in an isolated system remains constant.

Electric charge can be created and destroyed.

The total electric charge in a closed system can change over time.

Electric charge is always positive.

Conductors allow electric charges to flow freely, while insulators do not.

Insulators allow electric charges to flow freely, while conductors do not.

Both conductors and insulators allow electric charges to flow freely.

Conductors and insulators are the same in terms of electric charge flow.

The force remains the same.

The force decreases to one-half of its original value.

The force decreases to one-fourth of its original value (inverse square law).

The force increases to four times its original value.

An object has more positive charges than negative charges.

An object has more negative charges than positive charges.

An object has an equal number of positive and negative charges.

An object has no charges at all.

Ampere (A)

Volt (V)

Coulomb (C)

Ohm (Ω)

They repel each other.

They attract each other.

They have no effect on each other.

They neutralize each other.

Yes, an object can be neutral if it has equal amounts of positive and negative charges.

No, an object can only have a positive or negative charge.

An object can only be neutral if it has no charge at all.

An object can be neutral if it has more positive charges than negative charges.

A region around a charged object where other charged objects experience a force.

A type of energy that can be stored in batteries.

A measure of the voltage in a circuit.

A phenomenon that occurs only in magnetic materials.

Charge quantization means that electric charge exists in discrete amounts, typically as integer multiples of the elementary charge (e).

Charge quantization indicates that electric charge can vary continuously without restriction.

Charge quantization is a principle that states electric charge can only be negative.

Charge quantization suggests that electric charge is only found in certain materials.
