What are the two main components of the electrical system?

• A. Battery and Alternator
• B. Regulator and Fuse
• C. Starter and Alternator
• D. Transformer and Battery

Answer: (A)

An electrical system relies on a power source and a generator to keep energy available. The battery is the energy reservoir, supplying current when the engine is off or under demand, such as starting and running accessories. The alternator acts as the generator, producing electrical power while the engine runs and, crucially, recharging the battery so energy is available for the next start and for continuous operation of loads. A voltage regulator keeps the system voltage within safe limits to protect components, but it isn’t the primary source of energy. The other options involve protective devices or components used mainly for starting or specific electrical configurations, rather than the two main energy-providing elements. So, the battery and the alternator are the core pair that drive the electrical system.
