Algebra.Com's Answer #28951 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! current I in an electrical conductor varies inversely as the resistance R of the conductor. If the current is 1/2 ampere when the resistance is 240 omhs, what is the current when the resistance is 540 omhs? \r \n" ); document.write( "\n" ); document.write( "I=k/R \n" ); document.write( "Need to find \"k\". \n" ); document.write( "(1/2)=k/240 \n" ); document.write( "k=120 \n" ); document.write( "So the equation for this problem is I=240/R\r \n" ); document.write( "\n" ); document.write( "Now, what is the current when the resistance is 540? \n" ); document.write( "I=240/540 \n" ); document.write( "I=4/9 amp.\r \n" ); document.write( "\n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
