While taking photographs in Death Valley on a day when the temperature is 58.0C, Bill Hiker finds that a certain voltage applied to a copper wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is 88.0C? Assume that no change occurs in the wires shape and size.
How much current will be flowing through a 69m length of copper wire with radius 6.9mm if it is connected to a source supplying 10V?
Given that V= J/A-s and 1 Kwh = 3.6 x106 J, what does it cost to operate a window-type air conditioning for one hour if the unit requires a 10-Amp current at 110V and electric energy costs 5 cents per Kwh? Compute the cost at 5.0 cents/Kwh of operating an electric motor that takes 15 Amp at 110V.
What voltage is required to be applied during open-heart surgery to utilize a defibrillator for reviving a patient from cardiac arrest, given that the path's resistance is 0.500 kΩ and a current of 12.0-mA is necessary?
Although caution must be used in applying ρ = ρ0(1 + αΔT) and R = R0(1 + αΔT) for temperature changes greater than 100 °C , for tungsten, the equations work reasonably well for very large temperature changes. A tungsten filament at 20 °C has a resistance of 0.350 Ω . What would the resistance be if the temperature is increased to 2850 °C ?

The wiring in a house must be thick enough so it does notbecome so hot as to start a fire. What diameter must acopper wire be if it is to carry a maximum current of 35 Aand produce no more than 1.5 W of heat per meter of length?
While taking photographs in Death Valley on a day when the temperature is 59.0°C, Bill Hiker finds that a certain voltage applied to a tungsten wire produces a current of 1.000 A. Bill then travels to Antarctica and applies the same voltage to the same wire. What current does he register there if the temperature is −88.0°C? Assume no change occurs in the wire's shape and size.
