Algebra.Com's Answer #354978 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! The electrical resistance of a wire is directly proportional to its length. If a 36 foot long wire has a resistance of 9 ohm(s) find the resistance of a 48-foot long wire. \n" ); document.write( "----------------- \n" ); document.write( "It's 1/3 longer, so it's 1/3 greater. \n" ); document.write( "= 12 ohms \n" ); document.write( "------------ \n" ); document.write( "9/36 = R/48 \n" ); document.write( "R = 12 ohms \n" ); document.write( " \n" ); document.write( " |
