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

Short Answer

$E _ { L I N E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$ A 60-volt electric time clock circuit with several clocks connected in parallel has a 2-wire line voltage drop of 12.5 volts when the circuit is closed. Using Ohm s law, find the total resistance of the 2-wire line if a current of 10 amps exists. Carry the answer to two decimal places.
