PMMC type instrument
Understand the Problem
The question is asking about PMMC type instruments, which are commonly used in electronics for measuring electrical quantities. The inquiry likely seeks to understand what PMMC stands for, its applications, and how it operates.
Answer
Measures DC currents and voltages using angular deflection of a coil in a magnetic field.
A PMMC instrument is used to measure DC currents and voltages by observing the angular deflection of a current-carrying coil placed in a uniform magnetic field.
Answer for screen readers
A PMMC instrument is used to measure DC currents and voltages by observing the angular deflection of a current-carrying coil placed in a uniform magnetic field.
More Information
PMMC instruments are also known as D'Arsonval galvanometers and are known for their accuracy in DC measurements due to the precise movement of the coil in the magnetic field.
