An electrical substation had a sudden discharge arc event lasting 0.005 seconds. The event produced 768,000 volts that conducted 500 amperes to a nearby grounded metal strap and opened a 500 ampere protective breaker.
(a) How much power was produced by the electrical discharge?
(b) How much energy was in the discharge?
(c) How long could a 75 watt light bulb stay lit, if all the energy in the arc was used to operate it?
