9) The reliability of measuring instrument means :

the life of the instrument

the extent to which its characteristics remain linear

the degree to which repeatability continues to remain within specific limits

all of these

Answer is:

the degree to which repeatability continues to remain within specific limits

the maximum value of a physical quantity that can be measured

the highest reading of the scale

the minimum reading of the scale

the smallest amount of a physical quantity that can be detected by the instrument

Answer is:

a low resistance is connected in series

a low resistance is connected in parallel

a high resistance is connected in series

a high resistance is connected in parallel

Answer is:

Explanation:

To increase the range of voltmeter we need to connect a high resistance in series. So, that equivalent resistance is more, So, range is more.

decrease the multiplier resistance

use an instrument with a high internal resistance

use a shunt resistor

use an a.c. meter with a rectifier

Answer is:

it will not give a reading

its reading will not change

it will give a deflection in an opposite direction

it will burn out

Answer is:
