Algebra.Com's Answer #28917 by adamchapman(301)![]() ![]() ![]() You can put this solution on YOUR website! OK, so the current varies inversely with the resistance. We can write: \n" ); document.write( " \n" ); document.write( "where x is a fixed constant value. \n" ); document.write( "Rearranging: \n" ); document.write( " \n" ); document.write( "When I=230, R=1/2, and this tells us that x=230/2=115 \n" ); document.write( "so when R=540, \n" ); document.write( " \n" ); document.write( "Giving the solution I=62100 amps\r \n" ); document.write( "\n" ); document.write( "I hope this helps.\r \n" ); document.write( "\n" ); document.write( "I would be extremely grateful if you would send me your feedback on my help to adam.chapman@student.manchester.ac.uk. \n" ); document.write( " \n" ); document.write( " |
