$$E _ { LI N E } = \sqrt { E_ R ^ { 2 } + E_ X ^ { 2 } }$$

Short Answer

$$E _ { LI N E } = \sqrt { E_ R ^ { 2 } + E_ X ^ { 2 } }$$ The line voltage ( $E _ { \text {LINE } }$ ) is 120 volts, and the voltage of the reactance ( $E_ X$ ) is 60 volts. What is the voltage across the resistance ( $E _R$ )? Carry the answer to two decimal places.
