ارجوا الاجابة على سؤالي هذا ... ضروري جداااا

a resistance was rated at 20 ohms, and the measured current through this resistor was 8.2 A. the range of the ammeter was 10A. compute the watts dissipated in the resistor. the scale of the ammeter had 100 divisi**s and could be read with certainly to +- 0.5% divisi**. it was later found that the resistance of the resistor was 0.2% greater than the specified resistance and the ammeter read 1% **** than the true value. determine the known error in the computed power in watt and in percent of the computed power.
