Review Conceptual Example 7 as an aid in solving this problem. Aportable electric heater uses 14 A ofcurrent. The manufacturer recommends that an extension cordattached to the heater dissipate no more than 2.3 W of power per meter of cord length. What is the smallest radius of copper wire that can be used in the extension cord? (Note: An extension cord contains two wires.)
