Can anybody please give questions related to least count and zero error of ammetre and voltmeter ...
Please help class 10th

Answer 1

Least count

Max value of ammeter or voltmeter/ no. of divisions

Zero error

If the pointer of the ammeter or voltmeter is exactly at zero, when it is not connected to the circuit, then the instrument has zero error.

If the pointer is above the zero mark, the the zero error is negative.

The number of divisions it is above the zero mark are to be subtracted from the reading
