In this case

To work out the current you would
divide voltage by resistance to get the
answer
230 by 18 is about 12.77amps
which is about 2933 watts which is about
a kettle
voltage is the pressure at which current
is passed along a cable
the resistance is the opposing pressure
from a cable
and is related to material and surface area
