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 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 Ballistic galvanometer Explain its construction?
A ballistic galvanometer is used by electricians to measure an electric current. It is commonly used to test whether or not an electric current is present. A ballistic galvanometer consists of a meter that is attached to two probes, one positively charged and one negatively charged. This keeps the user from being electrocuted when an electric charge is present.
What is critical dumping of ballistic galvanometer?
Critical damping of a ballistic galvanometer refers to the minimum amount of damping required for the galvanometer's pointer to return to zero without oscillating after being deflected. This ensures a rapid but smooth response to changes in current, preventing overshooting or settling time delays in measurements. Achieving critical damping involves balancing the resistive and inductive components of the galvanometer's damping system.
What is figure of merit of a ballistic galvanometer?
It is defined as the current which produces a deflection of one scale division in the galvanometer and is given by, G= k/NBA where, k is the torsion constant. N is the number of turns in the coil B is the magnetic field and, A is the ares of cross section of the coil.

What are applications of ballistic galvanometer?
Ballistic galvanometers are used in applications where a very short-duration current measurement is required, such as measuring the charge of particles in particle physics experiments or determining the output of pulsed power supplies. They are also used in high-speed photography to capture events that occur in a very short period of time.

Why does the glass mirror used in ballistic galvanometer rotate?
The glass mirror used in a ballistic galvanometer rotates due to the Lorentz force acting on the current-carrying coil placed within a magnetic field. This force causes the coil (and the attached mirror) to rotate, allowing the deflection of the reflected light beam to measure the current passing through the galvanometer.
Why is the lamp and scale arrangement in a ballisitics galvanometer at a distance of 1 meter from the galvanometer?
The lamp and scale arrangement in a ballistic galvanometer is placed at a distance of 1 meter to ensure that the deflection of the galvanometer caused by the current pulse is accurately measured. Placing it at this distance allows for the angular displacement of the galvanometer's coil to be proportional to the charge passing through it, aiding in the precise measurement of the current pulse's magnitude.
