Question 824420: Solve.
The power that a resistor must dissipate is jointly proportional to the square of the current flowing through the resistor and the resistance of the resistor. If a resistor needs to dissipate 64 watts of power when 4 amperes of current is flowing through the resistor whose resistance is 4 ohms,find the power that a resistor needs to dissipate when 3 amperes of current are flowing through a resistor whose resistance is 7ohms.
