A student uses a digital ammeter to measure a current. The reading of the ammeter is found to fluctuate between 1.98 A and 2.02 A. The manufacturer of the ammeter states that any reading has a systematic uncertainty of ± 1 %. Which value of current should be quoted by the student? AB C D (2.00 ± 0.01) A (2.00 ± 0.02) A (2.00 ± 0.03) A (2.00 ± 0.04) A
