What is the ampere-hour rating of a lead-acid battery that can deliver 20 amperes continuously for 10 hours?
AI Explanation
The correct answer is C) 200 ampere-hours.
The ampere-hour (Ah) rating of a battery is the amount of current it can deliver over a specified period of time. In this case, the battery can deliver 20 amperes continuously for 10 hours. To calculate the ampere-hour rating, you multiply the current (20 amperes) by the time (10 hours), which equals 200 ampere-hours.
The other options are incorrect because:
A) 20 Ah is too low for a battery that can deliver 20 amps for 10 hours.
B) 40 Ah is too low for a battery that can deliver 20 amps for 10 hours.
D) 400 Ah is too high for a battery that can deliver 20 amps for 10 hours.
