You can put this solution on YOUR website!
the inverse proportion formula is y = k / x
\n" ); document.write( "k is the constant of variation.
\n" ); document.write( "when you keep V constant, then V becomes the constant of variation and you get:
\n" ); document.write( "k becomes V
\n" ); document.write( "y becomes I
\n" ); document.write( "x becomes R
\n" ); document.write( "the inverse proportion formula becomes I = V / R
\n" ); document.write( "if the current is 60 amperes when the resistance is 228 ohms, the formula becomes:
\n" ); document.write( "60 = V / 228
\n" ); document.write( "solve for V to get V = 60 * 228 = 13680.
\n" ); document.write( "that becomes the constant of variation because it doesn't change.
\n" ); document.write( "when the resistance is 120 ohms, the formula of I = V / R becomes:
\n" ); document.write( "I = 13680 / 120
\n" ); document.write( "solve for I to get I = 114 amperes.
\n" ); document.write( "that should be your answer.\r
