In a simple electrical circuit, the current in a resistor is measured as 2.5 ± 0.05 mA. The resistor is marked as having a value of 4.7 Ω ± 2%. If these values were used to calculate the power dissipated in the resistor, what would be the percentage uncertainty in the value obtained?

please help me, what is the solution for this one? thanks
i'm sorry, i post this in the advanced physics too, I'm confused where to post this.. hope you can help me...
