AI Thread Summary

Vptp does not mean the same as Vmax; Vptp refers to voltage peak-to-peak, while Vmax indicates the maximum voltage from zero to the peak. In a sine wave, Vmax is the voltage measured from the zero line to the peak value. Conversely, Vp-p measures the total voltage from the positive maximum to the negative maximum, which is twice the value of Vmax. This distinction clarifies the difference between the two voltage measurements. Understanding these terms is essential for accurate electrical analysis.

Does Vptp mean V peak to peak?

If so, no it isn't the same as Vmax.

If it was a sinewave, Vmax would be the voltage from the zero line to the peak value.

Vp-p would be the voltage from the positive maximum to the negative maximum or twice the voltage of Vmax.

Ah, makes sense. Thank you!

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...
