Explanation:

Question 1

An alternator works when the engine is running. It recharges the battery (as the battery is used for starting and other initial electrical needs) and provides power to electrical consumers (like lights, radio etc.) when the engine is running. It cannot do these when the engine is not running. The starter motor (not alternator) is responsible for starting the engine.

A hydrometer measures the specific gravity (related to the state - of - charge, not just the liquid level) of the electrolyte in a battery. A battery tester may need organization input for accuracy, a belt tension gauge measures alternator belt tension, and a multimeter can measure battery voltage.

CCA stands for Cold Cranking Amps. It is a measure of a battery's ability to start an engine in cold temperatures. Charged Current Amps is not a standard term for this rating, Cranking Amps (CA) is a related but different (less cold - specific) measure, and Charged Cranking Amps is not a recognized standard term.

Answer:

a. Recharging the battery while the engine is running.
d. Providing electrical power for all the electrical consumers while the engine is running.
