Question

In Europe the standard voltage is 230 V rms at 50.0 Hz. Suppose you take your 6.00-W electric razor purchased in the US to Rome and plug it into the receptacle (with an adapter to fit the receptacle but not to change the voltage).

What power P-Rome will it draw in Rome?

What rms current i-US will run through the razor in the United States?

What rms current i-Rome will run through the razor in Rome?

If you want to use the razor in Rome without damaging it by utilizing a voltage adapter, what would the ratio Np/Ns of the windings in the transformer's primary coil to those in the transformer's secondary coil within the adapter need to be?

What is the resistance R of your razor?
