A Clamp on meter works on the principle of Faradays laws of electromagnetic induction. When their primary conductor is connected to a.c. supply, a current flows through it. This current flowing through the primary conductor produces an alternating magenetic flux .This flux links with secondary winding through the magenetic core & induces an emf in it according to the faraday’s laws of electromagnetic induction.
