Peak inverse voltage.
Voltage is an electric potential difference, just like you have a gravitational potential difference between the top and bottom of a hill. A ball rolling down the hill doesn't use up gravity and a charge moving along a electric potential doesn't use up that potential. The difference in potential means that a charge at the higher potential has ...
