Two identical galvanometers are converted into voltmeter and millivoltmeter. As compared to the series resistance of voltmeter, the series resistance of millivoltmeter will be

A
equal
B
more
Correct answer
C
less
D
zero

Solution

For the millivoltmeter, more current needs to flow through the coil. Hence, the series resistance will be less.

Hence, the correct answer is option: 'C'.
