A 300 V voltmeter has an accuracy of ± 2% of full scale deflection. When the reading is 222 V, the actual voltage
lies between 217.56 and 226.44 V
lies between 217.4 and 226.6 V
lies between 216 and 228 V
is exact 222 V
Answer: Option
Explanation:

Error = ± 6 V. Therefore, the actual value would be between 222 ± 6 V.
