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( "
\n" );
