To maintain a galvanometer, regularly check and calibrate its zero position, clean the connections and moving parts, and avoid overloading the instrument. It's also important to protect the galvanometer from physical damage and keep it away from strong magnetic fields to ensure accurate readings over time.
The galvanometer constant is the factor that relates the deflection of a galvanometer to the current passing through it. It is usually given as the current required to produce a unit deflection (such as one full-scale deflection) on the galvanometer. To find the galvanometer constant, you can pass a known current through the galvanometer and measure the corresponding deflection, then calculate the constant as the current divided by the deflection.
A current would register on a galvanometer when there is a flow of electric charge through the circuit that the galvanometer is connected to. The galvanometer measures the strength and direction of the current passing through it, displaying this information as a deflection on its dial.
No, a galvanometer does not have polarity. It is a device used to detect and measure small electric currents. The deflection of the needle in a galvanometer indicates the presence and direction of the current but not the polarity.
By attaching a resistance in parallel connection with the galvanometer. Or when a low resistor connected in parallel with galvanometer ,the galvanometer is converted in ammeter. and the resistor is called shunt resistance.
The galvanometer was invented by Johann Schweigger in 1820. It is a device used to detect and measure electric current.
To connect a galvanometer to a circuit, first, ensure the galvanometer is rated for the voltage and current levels of your circuit. Connect the positive terminal of the galvanometer to the positive side of the circuit and the negative terminal to the negative side. Optionally, include a resistor in series to limit the current and protect the galvanometer from damage. Finally, ensure all connections are secure to maintain accurate readings.
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
The current is reversed in a galvanometer

Zero is the normal position of the galvanometer when there is no detection in process.

The galvanometer is very sensitive.
Ohms are the unit of measurement for resistance, so an ohmmeter is a device that measures electrical resistance. A galvanometer measures the current flowing through the resistance, so the two are related. To convert a galvanometer into an ohmmeter, one needs an external battery.
Since Galvanometer is a very sensitive instrument therefore it can't measure heavy currents. In order to convert a Galvanometer into an Ammeter, a very low resistance known as "shunt" resistance is connected in parallel to Galvanometer. Value of shunt is so adjusted that most of the current passes through the shunt. In this way a Galvanometer is converted into Ammeter and can measure heavy currents without fully deflected.
