Question

difference between galvanometer and ammeter
and what is magnitude ​

Answer 1

Answer:

The galvanometer and ammeter both are the measuring devices. The ammeter is the implemented form of the galvanometer which shows the accurate value of current passes through it in milliamperes or amperes.

what is galvanometer?

The galvanometer is the device used for detecting the presence of small current and voltage or for measuring their magnitude. The galvanometer is mainly used in the bridges and potentiometer where they indicate the null deflection or zero current.

what is ammeter?

The meter uses for measuring the current is known as the ammeter. The current is the flow of electrons whose unit is ampere. Hence the instrument which measures the flows of current in ampere is known as ampere meter or ammeter.

The following are the key differences between the galvanometer and the ammeter.

The galvanometer is the mechanical devices used for determining the magnitude as well as the direction of the current, whereas the ammeter is the electric devices used for measuring the magnitude of the current.

The galvanometer shows the direction of current flows in the circuit whereas the ammeter measures the magnitude of current flows through it.

The magnetic field is required for the working of galvanometer whereas it is not essential for the ammeter.

The accuracy of the galvanometer is less as compared to the ammeter.

The galvanometer is only used for measuring the direct current, whereas the ammeter is used for measuring the both the direct and alternating current.

The sensitivity of the galvanometer is more as compared to the ammeter.

The galvanometer is mostly used in bridge and potentiometer for knowing the zero current whereas the ammeter is directly connected in series with the circuit whose magnitude is to be measured.

what is magnitude?

Magnitude generally refers to the quantity or distance. In relation to the movement, we can correlate magnitude with the size and speed of the object while travelling. The size of the object or the amount is its magnitude. Like in case of speed, a car is travelling faster than a motorbike.
