Algebra.Com's Answer #595762 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! E=IR \n" ); document.write( "I=E/R This is the formula, and it is inversely.\r \n" ); document.write( "\n" ); document.write( "2.5 amps=350 volts/140 ohms. Now double the resistance, and you would expect the current to halve.\r \n" ); document.write( "\n" ); document.write( "x= 350 volts/280 ohms\r \n" ); document.write( "\n" ); document.write( "=1.25 amperes.\r \n" ); document.write( "\n" ); document.write( "It indeed is half as much. \n" ); document.write( " |
