Equation P = I2R Seems to suggest that rate of increase of internal energy in a resistor is reduced, if the resistance is made less. Equation P = V2/R seams to suggest just the opposite. How do you reconcile this apparent paradox?
A toaster has a Nichrome (a-4.5 10C) heating element that has a resistance of Ro 80 2 at a temperature T-20 °C. When the toaster is turned on, the resistance of the element
rises to 91 2 and its temperature is increased. Find the final temperature (in °C) of the heating element.

- Residential building codes typically require the use of 12-gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as large as 20.0 A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire could rise to a high temperature and cause a fire. (a) Calculate the rate at which internal energy is produced in 1.00 m of 12-gauge copper wire carrying 20.0 A. (b) Repeat the calculation for a 12-gauge aluminum wire.
