An electrical device is designed to draw 3.5 amps and operates in a voltage range of 22.0 to 24V. A 18 AWG copper wire is used to connect the device to a 24V power source. What is the maximum allowable length of wire (in m)? Assume the wire is maintained at room temperature.
The notation n AWG refers to the American Wire Gage scale, and it specifies the wire diameter according to d = 0.005 in x 92[(36-n)/39] where n is a whole number.
