Earth is the part of the circuit directly connected to
earth and is at absolute earth or zero potential while
nuetral is part of circuit may not neccasarily be at zero
potential

Answer / alekhya

Earth is nothing but ground,which is a combination of both +ve & -ve paricles(particles may be ions or electrons),whose potential appears to be zero.whereas neutral in the circuit provides a return part,and if there is any problem of high voltages in the circuit the neutral is connected to the ground.
