Battery puzzle?

Question

You have 4 batteries rated at 1.5V and 500milliamp hours.

What are their voltages and milliamp hours rating when connected in series and parallel?

Answer 1

I hate to do this to you but the batteries rating does not change whether connected in series or parallel so it will be

1.5V and 500mAh

each

however a parallel connection will give 1.5V at 2500mAh

and a series connection will give 6V at 500mAh

Answer 2

I agree with Stephen - mostly. I think he left a typo, which you may already have noticed. 4 X 500  makes 2000 and not 2500.
