The current in a conductor and the potential difference across its ends are measured by an ammeter and a voltmeter The meters draw negligible currents The ammeter is accurate but the voltmeter has a zero error that is it does not read zero when no potential difference is applied Calculate the zero error if the readings for two different conditions are 1 75 A 14 4 V and 2 75 A 22 4 V
