What is the basis of the function of a galvanometer?
The function of a galvanometer is based on the interaction between a magnetic field and an electric current passing through a coil of wire. When a current flows through the coil, it creates a magnetic field that interacts with a permanent magnet, causing a deflection of the needle on the galvanometer scale.
How do you maintain a galvanometer?
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.
What is galvanometer constant and how to find it?
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.
What are the merits and demerits of moving coil galvanometer?
The merits of a moving coil galvanometer include high sensitivity, accuracy, and ability to measure small currents. However, its demerits include limited range of measurements, susceptibility to external magnetic fields, and fragility of the moving parts.
Which circumstances would a current register on the galvanometer?
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.

What is a NULL Point of a galvanometer?
Its a point on the galvanometer where the galvanometer shows no deflection as no current passes through it.
Does a galvanometer have a reversed current or not?
The current is reversed in a galvanometer
Principle of multimeter?
Based on the principle of the D'Arsonval galvanometer, the main function of a multimeter is measuring a circuit's voltage, current, and resistance.
A galvanometer with a low- resistance shunt in parallel with its moving coil is?
A galvanometer with a low-resistance shunt in parallel with its moving coil is designed to measure larger currents than the galvanometer alone can handle. The shunt allows most of the current to bypass the sensitive coil, protecting it from damage while enabling a more accurate reading of high currents. This setup improves the range and utility of the galvanometer in various applications, allowing it to function effectively as an ammeter. The shunt's resistance is carefully chosen to ensure that the majority of the current passes through it, minimizing the effect on the galvanometer's measurement.

Why do you need to set a galvanometer to 0?
Zero is the normal position of the galvanometer when there is no detection in process.

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.
