SSC JE Electrical 2019 with solution SET-1 Relate ‘Reluctance with the following: A/m Weber/m Weber/A A-T/Weber A/m Weber/m Weber/A A-T/Weber ANSWER EXPLANATION DOWNLOAD EXAMIANS APP The reluctance of any part of a magnetic circuit may be defined as the ratio of the drop in magnetomotive force to the flux produced in that part of the circuit. It is measured in ampere-turns/Weber and is denoted by S.Reluctance = m.m.f ⁄ flux
