Volts and Amps for beginners

[(*steve*)]

It seems to me that almost every second thread has a poster who doesn't understand the relationship between voltage and current (and implicitly resistance) causing them to become highly confused about whether a 10A supply is going to overload their xxxx and burn it out.

Do we have somewhere to point these people, or alternatively can we come up with a reasonably sensible and readable explanation for these people (who are often totally convinced they're right)?

I'd start something, but I have my wedding anniversary today and I have to go...

OHM's Law

Steve,

allaboutcircuits.com has lots of explanations, have them see specifically OHM's Law Vol 1 Chapter 2 on this site.

or

electronics-tutorials.ws/dccircuits/dcp_1.html (I refer people to here)

Cheers,

B

There's even one on this very site:

There's even one on this very site:

Quite frankly, for some first time posters, even that is simply far to complex and technical.

lecture 9

I think its easy enough

If you come across any posts or make one that you think would be a helpful introduction, I can make them "stickies" (they stay at the top of the forum) or articles that we can direct people to.

Here's two more. These are more basic, but don't adequately describe circuits.

The problem is that they try to explain advanced concepts (charge, capacitance) without ever really touching on basic things like series and parallel circuits (or indeed the concept of a circuit)
