# Difference between voltage and current

I wish to know the basic difference between the terms 'voltage' and 'current' used in electrical engineering. I'd appreciate any responses.

what is difference between voltage and current
to be very simple for you to understand ...voltage or P.D is water level in tank and current is the flow of water through tap

Current is flow of electrons ,while voltage is emf caused by potential .hope m correct!!

Here's my explanation,

When two points have different electrostatic potential energies,we have a potential difference( P.D.) which we call voltage.

Now if these two points are connected, due to this difference, nature tries to equalize their potentials, or in other words make the P.D. zero. To do this, charge must flow from higher density to lower density. This charge flow is achieved by charged particles called electrons(other particles are too strongly bound to be able to translate). Obviously this not only depends on the difference between the points but also the path we provide for the flow of charge. The rate of this flow with respect to time is what we call current.

Nice ðŸ˜€ I have to admit though, If I was walking on the street and some random guy asks me the difference between current and voltage, I would be baffled for a while ðŸ˜”

Well i really liked this subject back in school ash and some of the old enthusiasm has stayed on....
• sauravgoswami
well said,man.A true explanation,i must say this has been one of the toughfest question a layman can quaetion an engineer
• phoneworks
Simply put to the lay man's understanding, VOLTAGE is pipe while CURRENT is the flowing water meaning that CURRENT Is the force while VOLTAGE is the force carrier.
