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 108 watts of power when 6 amperes of
Current is flowing through the resistor whose resistance is 3 ohms, find the power that a resistor needs to
Dissipate when 3 amperes of current are flowing through a resistor whose resistance is 7 ohms.
A) 126 watts
B) 147 watts
C) 21 watts
D) 63 watts
