Q

What is the ampere-hour rating of a lead-acid battery rated for a 20 hour capacity that can deliver 10 amperes continuously for 20 hours without dropping below 90% of its rated terminal voltage?

🔍 Key Concepts

• Ampere-hour (Ah) as a measure of battery capacity • Relationship: Current (amperes) × Time (hours) • Meaning of a 20-hour rating for a lead-acid battery

💭 Think About

• If a battery can supply 10 amperes for 20 hours, how would you combine those two numbers to express capacity in ampere-hours? • Think about what the '20 hour capacity' description is telling you: is it changing the math, or just describing the test period? • Compare the result of your calculation with each choice: which one directly matches current × time?

✅ Before You Answer

• Be sure you are multiplying amperes × hours, not adding or dividing them. • Confirm that the 20-hour rating is just the discharge period used to define capacity, not an extra factor to apply twice. • Check units: your final value should be in ampere-hours (Ah) and match one of the options exactly.
