Do Amps matter or is voltage more important?

SECOND LESSON......when to use the over-hand vs under-hand method albeit with left hand or right hand.....depends on one's preference......as applicable.......
BOB RENTON
Since my seminar is confined to electricity, the next lesson will appropriately be
 
Volts versus amps.

Volts is water in a hose.

Amps is the difference between a garden hose, and a fire hose.

Both move water (voltage)...but if the hose is too small it isn't moving enough water to put out a fire. In other words, low amps (garden hose) won't start your car (put out the house fire), but higher amps (fire hose) will.

It's all the same voltage. Amps is the QUANTITY of the voltage.
Not necessarily true.....iff (if and only if) the volume does nor exceed the pressure loss of the hose. You did not specify the volume; different hose diameters have different flow losses depending of volume. Similarly, Boyle’s law of pressure applies.....related to fluids...
More specifically, Boyle's Law can be expressed mathematically.

  • P₁ is the initial pressure of the gas.
  • V₁ is the initial volume of the gas.
  • P₂ is the final pressure of the gas.
  • V₂ is the final volume of the gas.
Just a thought for consideration.....

Not exactly sure what the pix and music is suppose to represent....never heard of these people b4. My original statement of teaching a seminar regarding AC and DC electrical fundamentals is still applicable.......interested?

It's lighthearted, Bob.... a pun on the discussion, nothing serious... fun ! Me, Interested in teaching ? No... I'd enjoy a discussion of one of my favorite topics, quantum physics, but for now.... I just wanna rock n' roll.

Who cares, Weren't we talking about electricity?
 
:rofl: The OP posted his original question last friday morning and hasn't been on the site since. Boy, getting an answer must have really been important to him. Or not. Meanwhile, How many of us have commented, some with good information and some with bad information. Good luck with your battery issue. Oh, by the way, @PurpleBeeper answered your question in post #2.

Think of it this way. If amps don't matter, you should be able to start your car with one of these simply because it has 12 volts. Nope ain't gonna happen. They are only 3 Amp/Hour batteries. Your starter may take 300-500 amps to crank the engine to start.

I'd be happy to discuss quantum physics, but without a computer capable of solving quantum mechanics equations, it gets difficult to represent. Similar to trying to solve three equations in three unknowns, simultaneously or a matrix algebra algorithm.......very difficult......without help........

First we should discuss how an ~80 yr old can claim to have never heard of a 52 yr old band with world wide notoriety. Abandoned on a deserted island perhaps? Something to ponder

With regard to the 52 YO band's music (?? ... if that's what its called), this is not my style or taste in music.....to me it's more noise than music. To me I'd prefer to listen to static rather than this crap....but....it depends on the listener........and I've pondered the subject for approximately 2 to 3 milliseconds.........

If you had never heard of them before, how would you deduce that their music is noise and crap? If you'd really like to listen to static, I have Lou Reed's 'Metal Machine Music' on vinyl that you can borrow.

I made the personal determination after approximately 20 seconds of listening to one of their recordings. I prefer quiet unobtrueive music with SOMETIMES CW blended in, depending on the group, like the EAGLES, and generally on SiriusXM when in the car but mostly for background...btw...thank you for your offer, but I'll pass........

I wonder if you'd only heard 20 seconds of just one Eagles song and didn't like it, if you'd still be listening to them?

I'm not a big AC/DC fan either, but can listen to some of their tunes. It isn't ALL static. :)

Good call on passing on the Lou Reed album, it's a waste of plastic.

You would think that a Mopar guy would like a band that plays a song with a Mopar engine theme
 
Maybe we ( I ) scared him away ?? :lol: Yes, amps matter View attachment 1851807
AMPS???? Literally and figuratively.......the pix shows amplifiers....for the sound industry.....their output is coincidencely, measured in watts connected into the resistance/impedance of speakers voice coil. Ohm's Law says P (watts)= I (current) x E (E).....but this in a electricial steady state condition. P (watts) in relation to a sound system is expressed over a range....20 hz - 20,000 hz at a given load...with a specified distortion level, not to exceed usually +/- 3dB. The resistance/impedance of the speaker's voice coil. REMEMBER. Sound/ music is basically an AC signal superimposed over a DC Voltage level. Sound level can also be expressed as decibels.
A unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on a logarithmic scale.
  • (in general use) a degree of loudness.
Now....how is the music produced / processed??? Does the amplifier use VACUUM TUBES OR TRANSISTORS to process the sound??? Many say tubes produce a "warmer" sound and are more forgiving when processing music with more noise........it depends on one's beliefs and expectations. Just a few points to ponder......punt....your turn........

I like tube 'amps' better :)

Note that a loudspeaker is not a resistor... :rolleyes:
It is a inductive, reactive load so the Ohm's law has little merit here except for bench testing not actual system operation...

Just my $0.02... :thumbsup:

I've experienced open circuit conditions in loudspeakers while playing both Montrose and Judas Priest records.
