How does armature reaction affect the main field flux in an alternator when the load has a power factor of zero leading?
1
Armature reaction distorts the main field flux and does not affect its strength.
2
Armature reaction distorts the main field flux and weakens it.
3
Armature reaction strengthens the main field flux and does not distort it.
4
Armature reaction weakens the main field flux and reduces the generated EMF.
