A portable electric heater uses 22 A of current. The manufacturer recommends that an extension cord attached to the heater receive no more than 1.9 W of power per meter of length. What is the smallest radius of copper wire that can be used in the extension cord? (Note: An extension cord contains two wires.) 0.421
