Identify the three essential components of an electrical circuit

Power source, conducting path, and a load.

A source of electrical potential difference or voltage. (typically a battery or electrical outlet) A conductive path which would allow for the movement of charges. (typically made of wire) An electrical resistance (resistor) which is loosely defined as any object that uses electricity to do work. (a light bulb, electric motor, heating element, speaker, etc.)

Ithink the answer is a or d.
