The main advantage of PMMC instrument is:
-
- High torque weight ratio providing high accuracy
- Possibility of using a single instrument for many different current and voltage ranges by use of shunts and multipliers
- Capability of measuring both a.c. and d.c. quantities
- Uniform scale
- High torque weight ratio providing high accuracy
Correct Option: C
The main advantage of PMMC instrument is capability of measuring both a.c. and d.c. quantities.
