Is it true that the voltage at a point means the quantity of charge at

AI Thread Summary
Voltage is not the quantity of charge at a point but rather the difference in electric potential between two points. It represents the difference in potential energy per unit charge. Voltage can also be understood as the work done in moving a charge through a potential difference. Electric potential and voltage are essentially the same, as both refer to the potential energy differences affecting electric charges. Understanding these concepts is crucial for grasping electrical principles.

is it true that the voltage at a point means the quantity of charge at that point?if not then what is voltage?
thanks

no, voltage is a difference between two points …

it's the difference in electric potential between two points

(and since electric potential = potential energy per charge, that means it's the difference in potential energy between two points, for a unit charge)

from the work energy theorem that means that the work done moving a charge q through a voltage difference V is the change in potential energy: Vq :wink:

i am not able to understand the term electric potential?Is electric potential and voltage means same?
thanks.

yes, voltage = potential difference = difference in electric potential = difference in potential energy per electric charge :smile:
 
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...
