- When current is passed throgh a galvanometer, the coil oscillates about its mean position before it comes to rest.
- To bring the coil to rest immediately, the coil is wound on a metallic frame.
- Now, when the coil oscillate, eddy currents areset up in the metallic frame, which opposes further oscillations of the coil.
- This inturn enables the coil to attain its equilibrium position almost instantly.
- Since the oscillation of the coil die out instantaneously, the galvanometer is called dead beat galvanometer.

What is the difference between ballistic and a deadbeat galvanometer?
A ballistic galvanometer measures charge by letting current flow through a coil and measuring the extent of its deflection. A deadbeat galvanometer is designed to quickly dampen the coil's movement to minimize oscillations, making it more suitable for accurately measuring steady currents.
What is differences between ballistic galvonometer and dead beat galvanometer?
A ballistic galvanometer measures total charge passed through the coil while the deadbeat galvanometer indicates steady state current. Ballistic galvanometers are faster but less accurate due to damping, while deadbeat galvanometers have a faster response time and are more accurate for measuring constant currents.
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.
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.
Does galvanometer have polarity?
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.

What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
What is the difference between the construction of a moving coil galvanometer and a ballistic galvanometer?
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.
