Algebra.Com's Answer #393904 by Theo(13342)![]() ![]() You can put this solution on YOUR website! P = E*I \n" ); document.write( "P is power measured in watts \n" ); document.write( "E is voltage measured in volts \n" ); document.write( "I is current measured in amps. \n" ); document.write( "motor data says 180 watts of power are being used and the voltage being applied is 120 volts. \n" ); document.write( "substitute for P and E in the equation to get: \n" ); document.write( "P = E*I becomes: \n" ); document.write( "180 = 120*I \n" ); document.write( "divide both sides of this equation by 120 to get: \n" ); document.write( "180 / 120 = I \n" ); document.write( "this makes I = 180/120 = 3/2 amps = 1.5 amps. \n" ); document.write( " |
