  • Energy-measuring resistor bank
    Patent number: 5339066
    Abstract: A resistor bank consisting of a group of resistors formed on the surface of die, all electrically connected together in parallel. All of the resistors have identical individual resistances, but each has a unique energy dissipating capacity. When an event subjects the resistor bank to a surge of current, some of the resistors blow out, thereby changing the resistance of the bank. By measuring the resistance of the bank before and after an event the energy of the surge can be determined.
