Algebra.Com's Answer #821505 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! If in a system a current of 20 amperes flows through a resistance of 20 ohms with an electromotive force of 100 volts \n" ); document.write( "-------------- \n" ); document.write( "E = I*R \n" ); document.write( "20*20 = 400 volts, not 100. \n" ); document.write( "================== \n" ); document.write( "150/20 = 7.5 amperes \n" ); document.write( " |
