If the pointer of the voltmeter is not exactly at the zero of the scale then the error is called _______.

The least count of a vernier calipers is 0.025 mm . If the 12th division of the vernier scale coinciles with a main scale division and the zero of the vernier scale is to the right of the zero of the main scale then the zero error is "______"

A voltmeter of resistance 998 Omega is connected across a cell of emf 2 V and internal resistance 2 Omega . Find the p.d. across the voltmeter, that across the terminals of the cell and percentage error in the reading of the voltmeter.

The least coun of a vernier calipers is 0.01 cm and if the zero mark of the vernier scale is right of zero of the main scale and the vernier coincidence is 7 when the jaws are in contact then the zero error is "_______" cm.

A voltmeter of resistance 994Omega is connected across a cell of emf 1 V and internal resistance 6Omega . Find the potential difference across the voltmeter, that across the terminals of the cell and percantage error in the reading of the voltmeter.

A voltmeter of resistance 995 Omega is connected across a cell of emf 3V and internal resistance 5 Omega . Find the potential difference across the voltmeter, that across the terminals of the cell and percentage error in the reading of voltmeter.

While performing an experiment to determine the equivalent resistance of two resistors connected in parallel, a student observes the pointer of voltmeter at position X when the key is 'off' and the same pointer at position Y when the key is 'on'. The correct voltmeter reading is :

if 17 divisions of the circular scale of a screw gauge are below the index line of the pitch scale then the zero error is "_______" circular divisions.
