Q

By what means is the capacity of a battery given in terms of a rating?

🔍 Key Concepts

• Difference between volts (electrical pressure) and current (amperes) • What a battery "capacity" really describes: how much charge or energy it can supply over a period of time • Common way marine batteries are labeled on nameplates (look at typical 12V lead-acid batteries)

💭 Think About

• Which unit includes time and relates to how long a battery can supply current? • When you see battery capacity in catalogs (e.g., 100 ___ at 20 hours), what is usually written in the blank? • Which options describe instantaneous electrical quantities and which describe a stored quantity over time?

✅ Before You Answer

• Identify which choice expresses current × time rather than voltage alone • Recall the standard capacity marking on a typical marine battery (e.g., 80 ___ at the 20‑hour rate) • Eliminate any option that is not commonly used on battery capacity nameplates or datasheets
