If a high voltage source strikes the ground the voltage is
disenpated though the ground in widening circles until it
is reduced to zero, if a person was standing near the
centre of the discharge there would be a voltage difference
between 2 points the closer to the discharge point the
higher the voltage, as an example cows have been killed
when they are close to a lightning strike but not hit by
the lightning, this is due to the voltage difference
between their legs, ie step voltage
