0.24 W
0.625 W
325 kW E. None of the above
Answer is Right!
Answer is Wrong!
The correct answer is C. 80 W.
The power dissipated by a resistor is given by the equation $P = V^2/R$, where $V$ is the voltage applied to the resistor and $R$ is the resistance of the resistor. In this case, $V = 25\text{ V}$ and $R = 1000\text{ Ω}$, so the power dissipated is $P = (25\text{ V})^2/(1000\text{ Ω}) = 80\text{ W}$.
Option A is incorrect because it is too small. Option B is incorrect because it is too small. Option D is incorrect because it is too large. Option E is incorrect because it is not one of the possible answers.
