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.
Answer Posted / Ravi Shankar Tiwary
To calculate the amperage (I) from the voltage (V) and power (P), use Ohm's law: I = P/V. Given that the power (P) is 1 kVA, and the voltage (V) is 220 V, you can find the current as I = 1000 W / 220 V = 4.55 A. However, it's important to note that this calculation assumes a power factor of 1, which may not always be the case for electrical appliances. For accurate results, consult the manufacturer or a qualified electrician.
