Hello all, could u pls help me with this question?
--- Quote ---In a simple electrical circuit. the current in a resistor is measured as (2.50± 0.05)mA. The resistor is marked as having a value of 4.7 ohms ± 2%
If these values were used to calculate the power dissipated in the resistor, what would the percentage uncertainty in the value obtained
A 2% B 4% C 6% D8%
