Lecture 29. Electric Forces and Fields

PHYS 1750: SELECTED TOPICS in PHYSICS

LECTURE 30. Electric Potential

18.1-2. Electric Potential

1. Electrostatic force is conservative

2. W = F*d = q*E*d = -Δ(PE) in uniform field E

3. Electric potential difference Δ(V) = Δ(PE) /q = E*d

4. Volt = J/C; Electric field often expressed in V/m instead of N/C

18.3. Point Charges

1. V=k*q/r

2. Superposition

3. PE = q₂V₁

18.4. Charged Conductors

1. Potential constant on the surface

2. Same potential in the interior
