Solving Ampere-Hour Problem for Camcorder Battery

In summary, the original AH rating of the battery for a 5 volt camcorder that now holds 20% fewer electrons than it did two years ago can be calculated by setting up a proportion of 0.5Ah/80 = x/100, which results in an original AH rating of 0.625Ah. The camcorder consumes 1A when operating and with a fully charged battery, a user can get 30 minutes of operation before the battery is dead.

Homework Statement


A 5 volt camcorder now holds 20% fewer electrons than it did two years ago. Today, with a fully charged battery, a user can get 30 minutes of operation before the battery is dead. What was the original AH rating of the battery? The camcorder consumes 1A when operating.

2. The attempt at a solution
I'm in my second class of EE and my professor didn't really teach us anything about problems like this. It says the answer is 0.625AH. I started out thinking since it uses 1A for 30 minutes, the current battery AH rating would be 0.5 so the original battery should be 20% more which is 0.6AH. I also did 1A = 1C/s so 30 minutes would be 1800C x 0.20 = 360C + 1800C = 2160C/3600C = 0.6 AH. Am i doing something wrong?

1A for 30 mins is 0.5Ahr
If this is what you get with only 80% of the original charge what would 100% equate to?

Haha wow. so i was just doing the percentage wrong. I set up proportions for a bunch of my other problems but didn't for this one. 0.5Ah/80 = x/100, x = 0.625Ah. Thanks.
 

FAQ: Solving Ampere-Hour Problem for Camcorder Battery

What is the Ampere-Hour problem for Camcorder Battery?
