Question 1069184: f the power dissipated in a resistor is 494 W when the current is 2.45 A, find the power when the current is 3.45 A.
[Hint: the power dissipated in a resistor varies directly as the square of the current in the resistor.]
Round your answer to 3 significant digits.
Answer by Boreal(15235) (Show Source): You can put this solution on YOUR website!
P=kI^2, where I is the current
494=k*2.45^2=6.0025 k
k=494/6.0025=82.3
------------------
P=82.3*3.45^2=979.57 or 980 W.
