You have no idea what the impedance of
the supply is with that PARTICULAR fluoro.

Most supplies are a very low impedance,

Most is irrelevant with faults.

How much power would be dissipated in a faulty 'electro' to cause
a
meaningful fluctuation in voltage?

Depends on the state of the supply to the fluoro.

If the mains wiring has caught fire & is providing power
through a layer of charcoal, you might be right.
In the other 99.999% of cases you are as usual talking out of
somewhere
dark.

Doesnt need to do anything even remotely
like that to see the fluoros flicker with a bad cap.

reams of your **** flushed where it belongs

Yet you're hopelessly unable to explain your point of view.

Everyone can see you are lying thru your ****ing teeth, as always.

Please quote your explanation from this thread then.

Go and find it yourself.

Several of us looked, there was none

I said that a bad cap can see the voltage
the tubes get produce flicker, particularly when the feed to the
fitting hasnt been done as well as it could be

too vague to be meaningful

or has a fault that
sees a higher impedance than normal

what fault do you think would produce that?

which doesnt produce
the flicker until the cap goes bad.

And an explanation is irrelevant anyway when removing
the cap is so easy to do and proves if the cap is the problem.

it proves no such thing of course. Disturbing wiring leading to no more flicker is 100x more likely to be down to a poor connection than a bad cap


Only pig ignorant lying bull**** artists like you two
would actually be stupid enough to proclaim that
no bad cap could ever produce any flickering.

I explained exactly how it could. I also said that it's unlikely in the extreme.

And you'll have to pardon us if we have noticed
that Adam sees a hell of a lot more faults than
you two will ever see and is much more likely
to know whats possible than you two clowns.

a) that proves nothing
b) as mentioned such a scenario is more likely due to disturbing a bad connection. A bad cap simply has nothing to do with it. They either
a) lose capacitance, causing no flicker, or
b) ESR rises, causing no flicker, or
c) go leaky, causing no flicker, or
d) arc over, blowing a fuse or fusing themselves. No further flicker.


Further down the thread you say
There can obviously be a poor connection that
doesnt see any flicker until there is also a bad cap.

PF capacitors in fluoros actually reduce current consumption, so they would marginally improve things in such a case, if at all functional. If thoroughly shot the problem causing flicker is the bad connection, not the cap, which is never going to draw enough current to cause this.

Like almost all your explanations, it's your fantasies, and on closer examination they don't stand up. Those of us with some experience in the relevant field know this from that start. You consistently resort to abuse and avoiding the question in a feeble attempt to defend your position, and your explanations when provided show that you've not thought it through.

Once a month you get something right. The rest of the time you waste everyone's time with your fool's talk.
