AC generator
in between stator , rotor rotates and cut the magentic
field by 0 ,120,240 degree it produces dC
current ,commutator is convert the dc into ac ,and we get
ac
generator is for generate ac current

I am an American living in Vietnam and I have recently gotten a refrigerator from Japan and it is rated for 100 vac, but the power here is 220 so I bought a voltage stabilizer it has a 1 kva output rating. Can you please tell me what the amperage is? I'm confused and without a working fridge.
