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
- C less
- D zero
Answer & Solution
Correct Answer
(C) less
Step-by-step Solution
Detailed explanation
For the millivoltmeter, more current needs to flow through the coil. Hence, the series resistance will be less.
