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
