What is an electric field?

An electric field is the region around a charged object where another charged object experiences a force.

Formula: E = F/q (in N/C or V/m)

• Vector quantity — direction from + to − charges.
• Field lines drawn from + to −, never cross, perpendicular to conductor surface.

For a point charge: E = kQ/r² (k = 9 × 10⁹ N m²/C²)

An electric field is the force-per-unit-charge region around a charged body, described by field lines pointing from positive to negative.
