power supply

This does not directly tell you how much energy the battery can store, but can be a more useful value in deciding how long a circuit will run from a battery. For example, a car battery might be rated for 50 Ah. That means in theory it could source 50 A continously for 1 hour and then go dead. In practise it''s never that simple, and there are various factors that effect
