Several in an enclosure could be a heat problem, so I'd prefer the watless dropper type when they have any in. Look on Ebay, there are much cheaper better ones. But buy them from a UK seller who is registered in the UK (not just posting from a port in the UK). Otherwise the distance selling regulations won't help you if they fail. Most of what I've seen on Ebay that I'd want to order, is from China etc. LED bulbs are plentiful on Ebay. There are loads of UK sellers who have imported thousands and sell them from this country, with our consumer protection laws applying. Royal Mail extorts a racketeering 'handling charge' for collecting any duty. Its pretty much put me off bothering. What are you talking about? A few years ago I ordered an electronics kit from Jaycar in Australia. The duty to be collected was about £4 - that and the Royal Mail 'handling charge' for collecting it came to more than 50% of what I paid for the kit! Its pretty much blackmail - cough up the extortionate charge or you don't get your goods - which will eventually be disposed of. By "duty" I assume you mean import taxes. That shouldn't occur unless the item is over about £30-£50. Secondly any decent seller will write it as "gift" and value "$10". Well Jaycar didn't, and I got mugged by RM. |

I glanced over it .... didn't see anything to go against my " *OPINION* " .... but I could be wrong!! If you read down a bit you see they list capacitors & inductors under linear loads. Here linear means e=Zi where Z is the impedence & e & i are the instantaneous voltage & current. Basically, you put a sine wave voltage in, you get a sine wave current with a possible phase shift out. Non-linear devices give current that has harmonics or has term like i^2, i^3 or v^2 etc. or where Z is a function of voltage or current. e.g. distortion to the sine wave other than a simple phase shift. Z /can/ depend on frequency but not voltage or current, so its a touch more messy if the input isn't a sine wave. For linear loads (1) pf = real power/apparent power, real power= RMS(e x i), appearant power = RMS(e) x RMS(i) and (2) pf = cos(phi) are equivalent. For non-linear loads (2) is less usefull so you either need a new term or you need to generalize from (1) which seems to be what was done. C'est la vie say the old folks. Ron |
