Study Notes
Electric Field Due to Various Charge Distributions
Infinite Long Wire
- The direction of the electric field due to an infinite long wire at a point near the wire is radial, emanating from the wire.
Uniformly Charged Circular Ring
- The direction of the electric field at the center of a uniformly charged circular ring is zero, as the electric field lines from each part of the ring cancel out at the center.
Uniformly Charged Infinite Plane Sheet
- The electric field due to a uniformly charged infinite plane sheet at a point near the sheet is perpendicular to the sheet and has the same magnitude at all points near the sheet.
Uniformly Charged Disk
- The direction of the electric field at a point on the axis of a uniformly charged disk and outside the disk is along the axis, away from the disk.
Uniformly Charged Sphere
- The electric field due to a uniformly charged sphere at a point outside the sphere is radial, emanating from the center of the sphere, and is identical to that of a point charge at the center of the sphere.
