Electrostatics 19 : Electric Potential 1 ( Mathematical Derivation )
Channel: Adam Beatty
Date: 17/07/2013

In this video I continue with my series  of tutorial videos on Electrostatics. These videos follow on from my tutorial series on 'Vector Calculus for Electromagnetism' and are in preparation for my tutorial series on 'From Electromagnetism to Optics'. 
Specifically in this video I introduce the concept of the Electric Potential also known simply as the 'potential'. A potential difference is known as a voltage. We see in this video that the potential can be viewed as a mathematical convenience in order to simplify the calculation of the electric field (since the potential is a scalar field). In a later video we see that in fact its physical significance is that the potential has units of joules per coulomb (electric potential energy per unit charge). This series is pitched at undergraduate level.


I hope it's of use!! Thank you for watching and I hope that this matches your requirements.
