With no disrespect, are you talking about resistance rather than voltage?
We're generally on 230v here in the UK for domestic applications but I doubt that answers your question (Stepped down over the years on most substations from 240v).
While I'm not a domestic fridge engineer the principals are the same for all:
V= I x R
V= Voltage
I = Current (Amps)
R = Resistance
So since we're all on 230v, the question would be; Does your fridge have a defrost load stated on the data plate?
If so you can use the above calculation to work out the resistance (which is what I believe you may be looking for)?
