SUMMARY
The direction of an electric field is determined by the nature of the charges involved. Electric field lines emanate from positive charges and terminate at negative charges. When a positive test charge is placed in the field, it experiences a force in the direction of the electric field, while a negative test charge experiences a force in the opposite direction. In the case of two plates, where plate A is at -200V and plate B is earthed at 0V, the electric field direction is from plate A to plate B.
PREREQUISITES

USEFUL FOR
Students of physics, educators teaching electromagnetism, and anyone interested in understanding electric fields and their applications in electrical engineering.
) on how to find the direction of a electric field, for example (right or left). I know it has something to do with a test charge but can anyone quickly explain it to me.
