Help me understand electricity please

[dreamblade]

Anode to self: The current discussion about electricity hertz my brain, although I will always pay ohmage to the great electric genius, Nicola Tesla.

Sparking debate about this Electrifying subject, enLightens all of us. Although there looks to be much Resistance to the Transmission of such knowledge, you have all Conducted yourself like gentlemen. No doubt if Telsa were to read this thread he would be all Amped up and Potentially lose his Load with great Frequency.

Or, he might get so depressed over all this that he would ride his megacycle over a wheatstone bridge and commit suicide by converting his potential energy into kinetic energy, and then suffering an inelastic collision with the ground.

seems for some people here the best way to explain it is be careful, a little man will jump out of the plug socket and bite you. If you keep sticking that knife into it.

 

[Lord Byron]

Larger light bulb = lower resistance = more current for the same voltage
Smaller light bulb = high resistance = less current for the same voltage
no light bulb = infinite resistance, Current = V/infinity = 0

A resistance of 0 means you shorted the power to ground, Current = V/0 = infinity

You equation of V=I*R is correct
The problem is that you think that larger light bulb = higher resistance, it is the opposite.

Thankyou bishop. Go to the head of the class and get called names

Actually, I figured that OUT FOR MYSELF shortly after my own post got me thinking better BUT YOU HAVE CONFIRMED IT.

I assumed bigger bulb means bigger resistance and the opposite is true.

Bigger bulb means bigger filament means more flow of electricity as there is more conductor to flow on so less resistance


Now, conceptually what is going on with the electrons?

In AC the current alternates as the generator ( not what it is called) that has negative then positive magnets attached is turned by water.

This causes a movement in the negative electrons as they are attracted then repelled BUT electrons do not travel as they stay in their own orbit.

This is also why AC cannot be stored but has to be used as it is made

Is this correct?


In DC the current is made chemically , which is why it can be stored, and the electons do travel as they hop down the line from one atom to another

Is this correct?

The hopping electrons (figure of speech here) must come from somewhere and that is why the plate wears down in a battery as the plate is where the electrons come from

Is this correct?



I need to impress a SP as she likes to talk about this stuff instead of talking dirty

she is a AC/DC kind of SP
