Question

Which of the following instruments is used for detecting electric charge?
(A) Ammeter
(B) Galvanometer
(C ) Electroscope
(D) None of the above

Answer 1

Hint : The instrument used for detecting the electric charge. It is used for measuring, detecting and finding the nature of charge. An Ammeter is an instrument used to measure current. Also the galvanometer is a measuring instrument for electric current.

Complete step-by-step solution:
Electroscope is an instrument used for detecting the electric charge. It is used for measuring, detecting and finding the nature of charge. We all know that there are two types of charge. That is, positive and negative. Mainly there are three types of electroscopes. They are pin ball electroscope, gold leaf electroscope and needle electroscope.
Ammeter is an instrument used to measure current. Also the galvanometer is a measuring instrument for electric current.
Therefore option (C ) is correct.

Note: The significant and major difference between galvanometer and ammeter is that ammeter shows only the magnitude of the current. Whereas the galvanometer can measure the magnitude as well as the direction of current.
