A toaster is rated at 580 W when linked to a 70 V source. What current does the toaster carry, and what is its resistance?
While taking photographs in Death Valley on a day when the temperature is 53.0°C, Bill Hiker finds that a certain voltage applied to a iron wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the similar voltage to the same wire. What current does he register there if the temperature is-88.0°C? Suppose that no change occurs in the wire's shape and size.
