thanks sir you explained simply

Thanks!

great vid

great sir ..osm

[@MrEpicPwnage1]

You're awesome

Hi Mr Dan, it is a typo at 05:09? should be From a RC perspective?

[@TranOfficial]

Great vid! Shouldn't it be Q=CV_0 for your initial charge while discharging?

[@DanFullerton]

Yup, good catch on the typo!

[@DanFullerton]

Nope, not a typo. When you begin dealing with AC (alternating current) there's a bit more to take into account.

I don't understand why potential difference changes over time. Why doesn't the battery maintain a constant potential difference?

[@DanFullerton]

+Jacob Smith The battery does provide a constant potential difference across its leads. However, the potential across the elements in the circuits isn't necessarily constant.
