Consider a portable electric blanket that runs on a 6 V battery. If you use copper wire with a 0.75 mm diameter as the heating element, how long should the wire be (in units of meters) if you want to generate 25 W of heating power? (Take the resistivity of the copper wire as p = 1.7 × 10¬8 N.m.) Answer:

Suppose the cost of an incandescent bulb is 28 cents and that electricity costs 10.5 cents/kWh. Compact fluorescent lightbulbs (CFL), while they are more expensive, use 1/10 of the power for the same amount of illumination. What would be the maximum cost (in dollars) of a CFL such that the total cost (investment plus operating) would be the same for both CFL and incandescent 60 W bulbs? Assume both lightbulbs run for 1000 h.
