In this lecture I have discussed the concept of shading ring an error in the energy meter. In shading ring I have discussed that shading ring provides additional lagging flux which when added to the potential coil flux then the angle between resultant flux and potential coil voltage will be 90 degree so that shading ring make the angle of delta equal to 90 degree by providing lagging flux in the energy meter. And in error in the energy meter we discuss the formulae of energy constant (K), Measured energy(Em), true energy(Et) and percentage in the energy metre
