The operating resistance is
The operating current is
To determine your washing machine's operating resistance you need to combine the formula for power with the equation for Ohm's Law.
Ohm's Law states that the current passing through a conductor is directly proportional to the potential difference applied to that conductor
Use the equation for Ohm's Law and replace the current,
This means that the resistance will be equal to
Use this value in the equation for Ohm's Law to determine the operating current current in normal use
