But superconductors don't break Ohm's Law. The resistance is exactly zero, so there can be current with no PD!

Voltage = Current x Resistance, or V=IR. That's Ohm's Law.

A superconductor, as the name implies, has super low, "almost" zero electrical resistance. That's why the voltage (V=IR) is "almost" zero.

The internal workings of a battery is an electrochemical process. Ohm's law does not apply because there is no physical "resistor" involved in the chemical reaction inside a battery. The internal discharge in a battery is also an electrochemical process. There is no physical "resistor" involved, so again Ohm's law does not apply.

Ohm's Law applies only when you connect the battery voltage to an external "resistive load".

[FromTheRafters]

But it is an empirical law, and he had no zero ohm resistors. It did not cover theory dealing with ideals.

Almost?

Like I wrote above, it is not relevant here in lead acid batteries. Tell me something that I don't know instead of pretending that I don't know something that I do.

From Wikipedia:

Ohm's law is an empirical law, a generalization from many experiments that have shown that current is approximately proportional to electric field for most materials. It is less fundamental than Maxwell's equations and is not always obeyed.

Yes, almost. You've read it right. Superconductor is still not a "perfect conductor". A perfect conductor will have 0 Ohm of electrical resistance. A perfect conductor will make "perpetual machine" a reality.

You spout crap.

Wow, are you like in 1st grade maths or something? You really need to speak to your teacher about your lunacy. 367.92W spread over a year! Let's make this easier for your little brain. Grab hold of something hot, it burns you. Now work out how much heat you absorbed, and arrange for that heat to enter your hand over 24 hours. Is it still sore? No. Your stupidity is the same bullshit I see in papers - "this cost the taxpayer 50 million!" Yeah but there's more than 50 million people, so you divide that.... Or, "humans generate 60 billion tonnes of CO2 a year!" But there's a lot of us. Each one generates a fraction of that.

We were discussing a Lithium battery, not something subject to extreme temperature changes.

[Commander Kinsey]

It has everything to do with Ohm's law - the resistance in the wires, charging circuitry, battery will prevent it being infinity amps.

[FromTheRafters]

Commander Kinsey used his keyboard to write :

Ohm was working with the relation of voltage and current with wires of differing materials. Resistance was the term for the ratio between them in his experiments.

Keep in mind that some circuits display negative resistance, seemingly defying Ohm's Law, but actually Ohm's Law simply does not apply to those devices which cause these anomalies. Batteries and some other circuits are not resistive conductors in the sense of Ohm's Law.

[FromTheRafters]

No, I don't. He used real world materials, not pie in the sky ideals like ideal sources and sinks -- empirical experiments. You can prove me wrong by showing empirical evidence of infinite current, resistance or voltage, but hurry, I haven't got all day.

Lithium batteries will have reduced capacity at freezing temperatures in winter. Lithium batteries will heat up if fast-charged. Lithium batteries will bulge if overcharged.

The unit is watt-hour, birdbrain. The unit watt (W) is the instantaneous power input. Watt-hour (Wh) is the unit for the energy delivered in one hour. Either you really deliver that energy in one second, one month, or one year, that energy is still calculated to use the unit "watt-hour".

367.92 watt-hour excess charging in a lithium battery will will cause the same damage either over a day, a week, a month, or a year, you birdbrain British moron. It will cause the same damage through internal chemistry inside the lithium battery.

[Commander Kinsey]

Childish spotting of a typo noted.

Bullshit. If I punch you once at 100mph, it will harm you more than 100 times at 1mph.

You'd be good at writing alarmist bullshit in newspapers.

[Commander Kinsey]

For your above claim to be true, the voltage of a Lithium battery must change with temperature. I find that hard to believe.

[Commander Kinsey]

A battery is actually a perfect cell plus a resistor in series. That resistor obeys ohm's law. Eg. if you draw 1 amp from a battery, or 2 amps from a battery, the voltage drop will double.

[invalid unparseable]

There is no resistor inside a battery. A battery is a cathode and an anode, separated by electrolyte. The internal resistance of a battery is a hypothetical parameter. There is no real resistor inside.

You are really full of shit.

The hypothetical internal resistance of a battery changes all the time. It doesn't obey Ohm's Law.

[invalid unparseable]

Because you know nothing about batteries. You spout nonsense from imagination. Why don't you Google and find out instead of having other people to correct almost everything you say?

[Commander Kinsey]

I want one of those big-ass CO2 lasers so I can burn holes in the neighbour's curtains.

I went to university for electrical engineering. I did four years of Advanced Calculus in university. What do you have?

Some people are smart without going to university, but not you.
