A voltmeter has least count 0.05 V.?

A voltmeter has least count 0.05 V.

While doing Ohm's law experiment, a student observed that

pointer of voltmeter coincide with 15th division.

what is observed reading ?

ans reading = 15 x .05 = 0.75

am i right ?

    the classic voltmeter is a Galvanometer. this is rated for the quantity of present day required to push the needle to finished deflection. There are a undeniable form of divisions on the face of the meter. The formula is this: present day or voltage for finished deflection divided by way of the form of periods on the meter = least count huge form in amps or volts

    I would say 14 x .05 V = 0.70 V, since the first division is at 0 V.

    no the correct reading would be 0.70 and observed would be 0.75
