What law describes the force between two charged objects, stating that the force is directly proportional to the product of their charges and inversely proportional to the square of the distance between them?

• Coulomb's Law

• Newton's Law of Universal Gravitation

• Ohm's Law

• Hooke's Law

The main difference between alternating current (AC) and direct current (DC) is:

• AC flows in one direction while DC changes direction periodically.

• AC changes direction periodically while DC flows in one direction.

• AC and DC both flow in one direction.

• AC and DC both change direction periodically.

Why is AC used in household electricity instead of DC?

• AC is more efficient for long-distance transmission.

• AC is safer than DC for household use.

• AC is cheaper to produce than DC.

• AC allows the use of transformers to change voltage levels.
