What does the galvanometer measure?

Answer: The galvanometer is an instrument that is taken into account for doing the eclectic current measurement 

• By the use of a galvanometer, one can measure two things the direction in which the current is flowing and what is the magnitude of the flowing current. 
• An important part of the galvanometer is its needle movement as it indicates the current and by which intensity the current is flowing is shown by the needle moment 

There are many different types of a galvanometer that have been created such as 

• Astatic galvanometer 
• Tangent galvanometer 
• Mirror galvanometer 

The most commonly used galvanometer in current times is the moving coil galvanometer.
