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

Short Answer

$$E _ { LI N E } = \sqrt { E_ R ^ { 2 } + E_ X ^ { 2 } }$$ If the voltage across the reactance ( $E _X$ ) is 50 volts and the line voltage ( $E _ { \text {LINE } }$ ) is 300 volts, what is the voltage across the resistance ( $E _R$ )? Carry the answer to one decimal place.
