With R being resistance, L being length, D being diameter, and k, the CONSTANT of PROPORTIONALITY, you need to use the formula: \"R+=+kL%2FD%5E2\"
\n" );
document.write( "Before you do so though, you need to convert the units from cm to mm, or vice-versa.
\n" );
document.write( "After finding k, substitute the cm or mm values for diameter and length to find R, the resistance. \n" );
