$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$

$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$ One 2-wire section of a 24-volt watchman clock signal system is operated through a 450-foot length of lead covered cable drawing 2 amps. The size of the conductor is number 18, and the diameter is 40.3 mils. What is the resistance of one conductor? Express the answer to the nearer whole number. $$\begin{array} { l l } C M = \frac { K L N } { d ^ { 2 } } & \\&\text { where } N = \text { number of wires } \\& K = \text { constant } ( 10.8 ) \\& L = \text { length of one wire infeet } \\& R = \text { resistance in ohms } \\& d = \text { diameter in mils }\end{array}$$
