Calculate what is the necessary length of wire

Reference no: EM13670754

A piece of Nichrome wire has a radius of 7.6 x 10^-3 meter. It is used in a laboratory to make a heater that dissipates 320 Watt of power when connected to a voltage source of 120 Volt. Ignoring the effect of temperature on resistance, calculate the necessary length of wire.
