Introduction • Large issue to address is the connection between the electric potential and electric field. • The potential and the filed are not two independent ideas, merely two different perspectives how the source charges alter the space around them.
Finding the Potential from the Electric Field • First, the potential energy of the probe charge q and the source charges, divided by q, gives the electric potential • Second, the change in the potential energy is equal to the work done by the electric force • Third, the electric force is linearly proportional to the field. • Then the potential difference between two points in space is () ( ) f i f i s s s ss s fi s s s U VU V q q UW if F d s Fq E VV s V s VE s f o r t h e uniform electric field E ds ≡= Δ= = = = Δ
