A transformer on no-load is switched on to a source of voltage. It will draw a current _______
1
which is the same as the steady-state magnetizing current
2
which is several times the steady-state magnetizing current, depending upon the initial state of the residual flux in the transformer core
3
which is several times the steady-state magnetizing current, independent of the initial state of the residual flux in the transformer core
4
which is twice the steady-state magnetizing current provided the core has no residual flux
