Wowzers!! Seems like a lot, but when it starts to click you realise it's simply about knowing what current, resistance and potential difference are. How they relate to each other (Ohm's Law). How they apply to series and parallel circuits. And finally how some components don't follow Ohm's Law (bulbs/lamps, diodes, LDRs and thermisters). That's all folks. See you around and don't forget to thumbs up if you like. Decks with no reviews or negative reviews get taken down after a while. This isn't youtube; we don't do bad science. And after this lot, you won't do bad at science either.
