AI Thread Summary
The discussion highlights the drawbacks of an ideal clamper, particularly focusing on the behavior of the capacitor when input voltage decreases. It is noted that in an ideal clamper, the capacitor's voltage can change, which may not be desirable in certain applications. Participants express confusion about whether this characteristic is beneficial or problematic. The conversation also requests a link to an example circuit for better understanding. Overall, the drawbacks of ideal clampers revolve around their voltage behavior under varying input conditions.

What are the drawbacks of ideal clamper ?

Some body told me that in case of ideal clamper , capacitor does changes its voltage even if i/p voltage is decreased.
What i think is isn't it good that clamper is ideal.

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...
