Summary

Like mass, electric charge is a fundamental property of matter. The unit of charge is the Coulomb (C).

An electric charge, as a point in space, creates a disturbance called an electric field.  It is a vector field (intensity or magnitude and, direction at any point in the field) represented by E.  The unit is the Volt per meter [V/m].

The electric field vector E created by a charge, Q1, at point P in space is defined by:

  • Its direction:  The field created by Q1 is aligned with charge Q1 .  It is directed towards the charge…
