    Electric Frequency
AI Thread Summary
Different countries utilize varying electrical frequencies, such as 50Hz in Malta and 60Hz in the USA, which can impact the efficiency and performance of electrical devices. Higher frequencies, like 60Hz, can reduce the size of transformers and motors, leading to lighter and more compact designs. Conversely, 50Hz systems can be more efficient for certain types of power generation and transmission over long distances. The choice of frequency also affects the compatibility of appliances and can influence energy losses in the system. Understanding these differences is crucial for international equipment compatibility and energy efficiency.

hey,

as you know several countries have different voltages which they give to a normal household. Ie in our country Malta is 240Volts and in USA around 110Volts.

I also read that they have different frequencies. (e.g. Malta =50Hz and USA=60Hz)

Could anyone state advantages or disadvantages
at having certain frequencies?

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'

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...
