the voltage in a circuit is given by the equation V = square root of PR, where P is the power in watts ans R is the resistance in ohms. if the voltage in a circuit is 120 volts and the circuit produces 1500 watts of power, what is the resistance in the circuit
\n" ); document.write( ":
\n" ); document.write( " \"sqrt%28P%2AR%29\" = V
\n" ); document.write( "Solve for R
\n" ); document.write( "P*R = \"V%5E2\"; squared both sides
\n" ); document.write( "R = \"V%5E2%2FP\"; divided both sides by P
\n" ); document.write( ":
\n" ); document.write( "Find R when V=120 and P=1500
\n" ); document.write( "R = \"120%5E2%2F1500\"
\n" ); document.write( "R = \"14400%2F1500\"
\n" ); document.write( "R = 9.6 ohms
\n" ); document.write( ":
\n" ); document.write( "One way to check our solution, is find the current; I = V/R; I = 120/9.6 = 12.5 amps
\n" ); document.write( "We know power = volts*amps:
\n" ); document.write( "P = 120*12.5
\n" ); document.write( "P = 1500 watts
