Q

The capacity of a storage battery is measured in what units?

🔍 Key Concepts

• Electrical capacity vs. electrical pressure (what each one represents) • How long a battery can deliver a certain current • Difference between instantaneous current, voltage, and stored charge/energy

💭 Think About

• Which unit tells you how MUCH total electrical charge a battery can deliver over time, not just how strong the push is at any instant? • Think about how battery manufacturers describe how long a battery will last at a given current draw (for example, running a device for 10 hours at 5 amps). What unit do they use? • Which choice represents a combination of current and time, rather than just one or the other?

✅ Before You Answer

• Identify which option is a unit of voltage (electrical pressure) and rule it out for capacity. • Identify which option is a unit of current (flow at an instant) and rule it out for capacity. • Look for the unit that directly combines current and time, since capacity is about how much current can flow for how long.
