a) The time rate at which charge flows through the area is defined as the electric current. b) The resistance of a conductor is proportional to the voltage difference across the conductor and the current flowing through it. c) The radius of a Nichrome wire is 0.32 mm. Hence the resistance per unit length of this wire is about 3.1 0/m d) For a metal, the resistivity versus temperature curve is liner over a wide range of temperature, and resistivity increases with increasing temperature. e) An electric heater is constructed by applying a potential difference of 120V across a Nichrome wire that has a total resistance of 12.00. Hence the power rating of this appliance is 1.44 kW.
