Algebra.Com's Answer #393731 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! find the current in a circuit if the power is 500 w(watts) and the resistance is 25 ohms. round off your answer two decimal place. use formula i=p/r \n" ); document.write( "------------ \n" ); document.write( "Using i = p/r \n" ); document.write( "i = 500/25 = 20 amperes \n" ); document.write( "Any reason you couldn't do that? \n" ); document.write( "-------- \n" ); document.write( "Actually P = i^2r, not ir \n" ); document.write( "--> i = sqrt(20) =~ 4.472 amps \n" ); document.write( " \n" ); document.write( " |
