Control Relay Usually refers device with contacts that open and close
electromagnetically, but solid state control relays are also
available. EMF stands for electromotive force.This equal approximately 6. Control relays typically handle smaller currents than
contactors, but are capable switching more rapidly.
Coulomb’s Law law that states that charged objects attract repel each
other with force that directly proportional the product
of their charges and inversely proportional the square the
distance between them.
