Weird resistance reading; why?

[Cantabile]

I have an iClear 16 on an MPV. The MPV will give the resistance of the clearo. It is reading 4.8!!! I don't understand why or even how, when it's supposed to be around 2.1 (or might even be 1.8). The MPV will give a more sensible reading on other clearos, so it must be something wrong with the clearo, but what?

I noticed, because I was rereading one of Plenty's explanations of vv and vw, and wanted to give the algebra a go and play with my watts!

Hmm ... an iclear16 is usually 1.8 ohms IIRC. Is it screwed on properly? If it's not making proper contact with the battery it will read higher. Is it quite old? If the coil is crudded up that can cause a higher reading too.

I suppose it is getting on a bit now I think about it. I had done a dry burn, so the coil looked OK, but I could really only see the top coil and not the one beneath. It is def. screwed on all right. Must be age and crud, then

Thank goodness I have spare coils!

I have no understanding of electricity at all, though I've tried to learn many times in my 50+ years, to my embarrassment.

haha nor me, I'm learning through trial and error as I go along

You're doing a good impression

i even did a kind of Foundation science course with the OU when dd was a baby which covered all that stuff. I got 70% for my physics paper!! A friend of ours, an engineer, was explaining it to his 9yo son who understood what he was on about! but I didn't. Electricity is still a mystery.

Do you think it's actually magic, and there are a lot of people who've been duped into thinking they understand the rules - which were actually made up by Edison, Tesla and Ohm (who had got together and harnessed the power of lightning, which really is magic)?

Yes, of course it's magic! Edison, Tesla and Ohm were all wizards who could control the tiny electronic people who run down the wires and sometimes rub themselves together to create heat
