MCQ
What is moving coil galvanometer used for?
  • A
    Measurement of voltage only
  • B
    Measurement of resistance
  • C
    Measurement of small currents
  • D
    Measurement of electric field

Answer

  1. Measurement of small currents

Explanation:

Moving Coil Galvanometer is an instrument used for the detection and measurement of current.

It is sensitive instrument and can measure current even if it is only a few microamperes.

It was invented by Johann Schweigger in the 1800s.
