A basic electrical circuit contains

• A. A power supply connected to a load via conductive wires
• B. A circuit with no power source
• C. A single component without a load
• D. A closed loop with no path to ground

Answer: (A)

A basic electrical circuit requires a source of energy, a conductive path, and a load so current can flow in a closed loop. The option describing a power supply connected to a load via conductive wires includes all three elements, showing energy moving from the source through conductors to the load and back, which is exactly how a simple circuit operates. The other descriptions miss essential parts: without a power source there’s no driving force for current; without a load there’s nothing to consume the energy; and a closed loop without a load or source wouldn’t form a usable basic circuit. Grounding isn’t required for the basic operation of a simple circuit, but having a power source, conductors, and a load in a closed loop is what defines it.
