-- In electricity laboratory, we use some instruments such as ammeter and voltmeter to achieve an electric circuit, during one of the experiment the ammeter was reads 50 mA on its 125 mA range while the voltmeter reads 40 V on its 50 V range. The two instruments are guaranteed to be accurate within + 2% at full scale deflection. Determine the limiting error of the power calculated?
