The radius of the circle is
a
cm and the angular velocity ω radians/second. The constant charge velocity
aω
is less than the light speed
c
. The plot shows the retarded scalar potential per charge unit (esu) with the dimension
-1
cm
. The retardation delay is negligible if the observation point
{x,y,z}
is near the charge position. The time dependent scalar potential is averaged over time.
