Earth is a safety connection to the ground, while neutral is a current-carrying conductor.

• Earth is used for safety purposes to prevent electric shock by providing a path for current to flow into the ground.

• Neutral is a current-carrying conductor that completes the circuit and carries current back to the source.

• Earth is typically connected to the metal casing of appliances for safety.

• Neutral is connected to the center t...read more

Insulators prevent the flow of electric current, while dielectrics can store electric energy.

• Insulators do not allow electric current to pass through them

• Dielectrics can store electric energy when placed in an electric field

• Insulators are used to separate conductors and prevent electrical leakage

• Dielectrics are commonly used in capacitors to store and release electrical energy
