🔍 Key Concepts

• Ampere-hours (Ah) as a measure of battery capacity • Relationship: Current (amps) × Time (hours) • Units: making sure hours and amperes are used consistently

💭 Think About

• If a battery can deliver a certain current for a certain number of hours, how do you combine those two numbers to express capacity in ampere-hours? • Try writing a simple formula using the given current and time, then check if the result matches any of the answer choices. • Think about whether the capacity should be larger or smaller than the current alone, given it can deliver that current for several hours.

✅ Before You Answer

• Confirm you are multiplying amperes × hours, not dividing. • Check that you are using the full 10 hours in your calculation. • Verify that the final number keeps the proper unit: ampere-hours (Ah).
