Potential

AI Thread Summary

The discussion centers on the concept of potential in physics and its variability with changes in coordinates, despite being classified as a scalar. Participants express confusion over the relationship between scalar quantities and coordinate transformations. The need for more detailed explanations, including equations and references, is emphasized to clarify the topic. The conversation highlights the importance of understanding how potential is defined and measured in different coordinate systems. Overall, the thread seeks to unravel the complexities of scalar potential in relation to coordinate changes.

Welcome to the PF.

Please post much more detail about your question. It makes no sense with such a brief question. Can you provide some links to equations and other informative web pages?

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Electromagnet magnetic field issue'

Hi Guys We are a bunch a mechanical engineers trying to build a simple electromagnet. Our design is based on a very similar magnet. However, our version is about 10 times less magnetic and we are wondering why. Our coil has exactly same length, same number of layers and turns. What is possibly wrong? PIN and bracket are made of iron and are in electrical contact, exactly like the reference design. Any help will be appreciated. Thanks. edit: even same wire diameter and coil was wounded by a...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
