Please provide details such as:
- current drawn
- lead current rating and length
- motor's speed/power as a function of voltage

You do my request first, speak to the service desk of your manufacturer, let
me know who it is and I'll give you the number.

What position? I can guess some positions that you are
unlikely to be qualified to fill.

If you're going to troll, you're going to have to work harder than that.


Which manufacturer?

You give me all of your personal details and I'll think about giving out my
personal information on Usenet.

If the petrol motor isn't made to a budget, then
I certainly can't afford one!

Your personal finances are your own affair, I shan't comment on that.

You've missed the point

Did I?????????

Very clever ........ not.

Well, if you're going to be a dick about it, you'll get dickhead answers.



An explanation please other than cut and paste on something which is
'sort of relevant but again proves that a very little knowledge is a very
dangerous thing.

It explains electrical resistance and the effect that it has on current,
such as passing through an extended cable. Do you need it spoon fed?

You know I'm right, you're now just trying to find a weasel way out of it,
looking for a techincality.


I know that a little knowledge is a very dangerous thing, and you have 'a
little knowledge'........ Stop digging.

If you knew more, you would take great delight in 'shooting me down in
flames', instead of that, you are showing everybody just how much you DO NOT
know :-))

Kind regards.


Mike

Really, you've blustered about knowing a lot, but spoken very little,
actually nothing about it. So stop pretending that you know something and
actaully provide some evidence that what I have said is wrong.

But you won't, because what I have stated is correct. So come on put up or
shut up.

I take that as a bow out that you know sod all.

Don't you wish you had kept your trap shut in the first place?

You must be a new boy here otherwise you would have teamed up with 'The
Owners' and shot me down in flames :-))

Stick around, we can take the **** out of you again.

As I say when I come off correct again, "Next please"

:-))

(Don't bother to respond and dig deeper, you have proved you know too little
and anything you say now will be laughed at)

Well, I'll take that as you won't "put up" and show any proof to dispute
what I have stated and you're to stupid to know when to "shut up".

You cant' have it both ways, you either state some facts or carry on
drinking your rum old man. Now unless you've ygot some facts to back up your
ramblings, go back to your bottle.

Excuse me, but from an earlier posting of yours you state ""The resistance
in the cable reduces the performance of the
motor as well.""

I, and others have asked for clarification, You have failed to supply this.

Like I said above "Don't bother to respond and dig deeper, you have proved
you know too little and anything you say now will be laughed at"

I rest my case.

Please provide details such as:
- current drawn
- lead current rating and length
- motor's speed/power as a function of voltage

You do my request first, speak to the service desk of your
manufacturer,

You are making general claims that I (and others)
disprove weekly. I am not making any claims.

It is up to the person making a claim to prove it, not
up to other people to disprove it.

If you don't understand that then I'll claim the moon
is made of green cheese and, when you dispute it, I'll
demand that you refute my claim!

I've only just noticed this interesting thread. Putting in my pennyworth...
It is many years since I studied electrical theory so if anyone want to
correct anything I say please feel free :-)

1. The ability of a conductor to carry current is proportional to its cross
sectional area.
2. The resistance of a conductor varies with temperature (to a lesser or
greater degree depending upon the material) with some materials resistance
increases with temperature but with others it decreases.
3. Inductive effects can be a problem with long cables depending upon the
material used to make the conductor and any surrounding conductors which
'may' contribute a dampening effect. If a cable is left wound on a reel this
will have a larger inductive effect than if the cable is laid out straight.
A wound cable is also not recommended as any heat loss in the cable cannot
readily escape, so if a cable is heavily loaded this could cause it to heat
up and possibly melt.

In other words running an extension cable rated for 15 Amps at mains AC
voltage can safely and without problem run an appliance of up to 230 x 15 =
3450 watts (3.45 kW).

The maximum length of the extension cable is a function of the resistance of
the cable (should be negligable) and inductive resistance (again should be
negligable). Without exact figures for the parameters of the cable I suspect
these factors are unlikely to be an issue with modern copper cables. This
may have been an issue years ago with poor quality cables with impure copper
or an old extension cable that had been 'bent' so many times the copper
conductor was starting suffer from micro fractures?

I once did an experiment (outdoors) feeding an electrical kettle with a
cable rated at 2 amps. It was heavily overloaded but surprisingly the cable
just got hot and limp. The kettle eventually boiled too, but it took much
longer than normal, so there were significant losses in the cable. Pushing
it to the limit I added a second electrical kettle to the load. This time
the cable melted and failed with a nice big flash!

So while there is an element of truth in the original posters comments, I
very much doubt there would be any significant losses running an electrical
mower on a modern, good quality, extension lead that was within rating.

A slight tangent:
As power is given by voltage x current the same power can be delivered by
increasing one of these parameters and lowering the other. However, since
the maximum current that can be delivered through a cable depends on its
cross sectional area then using a higher current rather than higer voltage
is not cost effective as it uses more conductor to transmit a given power.
So high voltage and low current is prefered. That is why pylon wires are
such high voltage (used to be 143,000 volts as I remember?). However, with
higher voltage another factor comes into play - corona discharge. As pylon
wires are not covered in insualtion electrons at high voltage have a
tendency to jump off imperfections on the surface of the cable into
surrounding air molecules or water molecules. The effect is more pronounced
in foggy weather when this effect can be audible as a "zizzing" sound.

It is indeed, certainly regarding electricity. A former associate of mine
once made such an error. I dropped him off outside his flat one evening and
we noticed the remains of a burnt out mattress outside his (open) window. We
went inside and his flat was very black, sooty and everything well
scorched - and very wet courtesy of the fire brigade! It transpired that he
had made himself an electrical extension lead using twin and earth cable!!!
However, unlike flexible cable, the solid cores of the twin and earth did
not like being moved around and being flexed, so over time one had
fractured. The fracture got hot enough to melt the cable and ignite the
carpet under his bed and the whole lot went up in flames. Needless to say he
didn't have any smoke detectors or contents insurance either. Frankly he was
lucky to be alive.
