Is a Battery AC or DC? Explained in Simple Terms
When it comes to battery capacity, it is important to understand whether the battery operates on direct current (DC) or alternating current (AC). A battery can be either DC or AC, depending on the power source it is designed for. DC batteries, also known as direct current batteries, provide a constant flow of current in one direction.
how fast does the alternator charge the battery?
The terminal voltage going down to 13.1v suggests the battery is not charging, and may be discharging, unless the battery is very low. The alternator or the battery is probably in poor condition. The alternator will charge the battery at a constant voltage (usually 13.8, or 14.2), and electively never a constant current.
Your lab partner says that a battery provides not a source of constant ...
This causes the flow of current through the circuit. The battery provides constant voltage across the circuit. The current in the circuit does not remain constant because of various resistances in the circuit. If the electron passes through the resistance of high value then the flow of the current becomes slow but becomes fast for low resistance.
