SN7400 is a chip consisting of very many circuits, each of which could be drawn out by the designer and each of which would obey ohm's law. To think otherwise is just silly. The original question was regarding a simple circuit using a battery and some resistors. This WILL involve ohm's law - or else they won't learn anything worthwhile. Anyone wanting to learn basic electronics will absolutely be working with ohm's law, otherwise they are just fooling around with stuff without really understanding what's happening. I made my living with this stuff - and not by not understanding it at a basic level.

There never was and could never be an example of electricity flowing in a circuit that doesn't obey Ohm's law. It's basic - like gravity. In ac circuits it gets more complicated because of capacitive and inductive reactance, but Ohm's law always applies. Always will too. Beginners may flounder, but the basic laws of nature don't change.

All the textbooks we used expressed it that way - but that was a looong time ago. I went to electronics school in 1965 - 1968. That was in the last of the vacuum tube days. Old Mr. Ohm's law still works though! I suspect it always will.

For sure you will be using ohm's law - the relationship of voltage, current, and resistance. Voltage is usually shown as E (electromovitve force), Resistance as R, and Current as I (I don't know why) E/R = I I x R = E Like a nine volt cell connected to a nine ohm resistance will allow one amp of current to flow.

It seems to me that nothing ends up inside the ballon except the air you blew into it.

I've read (ok, skimmed) through all these pages and it seems like there are no first person, compemtorary accounts of Jesus - much less any collaborating ones. I would think if the people back then would have actually thought they were living amoungst a god, or god-like person they would have made a real big deal of it. Wouldn't they have done something similar to what the Egyptians or Maya did - write accounts of it in stone or erect monuments of some sort? If all we have is verbal second hand stories by church people (with a vested interest in keeping the stories going) to use as evidence, I think the whole thing is just a fable. Not that fables are bad or not to be taken seriously, just not to be taken as any kind of literal truth. Aesop's fables are useful, but rabbits and turtles don't really talk to each other - and when people die, they are dead. They can't become un-dead.

Irony magnets could come in handy sometimes.

I remember - many years ago - watching a show on tv concerning the Titanic. They were claiming that the steel plates of the hull were made of poor quality steel that was too brittle, and that the cold water made them even more so. When the ship hit the iceberg it cracked instead of just denting. Jim S.
