You apply a potential difference of 45 volts between the


you apply a potential difference of 4.5 volts between the ends of a wire that is 2.5 m in length and .654mm in radius. the resulting current through the wire is 17.6 A. what is the resistivity of the wire? You are asked to wind a heater coil out of nichrome wire. Nichrome wire has a resistance per unit length of 1.6 ohm/m. The heater must have a power rating of 45 W and is to be placed in series in a circuit with a 12 v battery. What length of nichrome wire will you use?
