The Answer of $E _ { L I N E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$ The four dry cells are connected in series as shown. Find the total resistance. Carry the answer to three decimal places.

ELINE=ER2+EX2E _ { L I N E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }ELINE​=ER2​+EX2​​

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