What does electromagnetism have to do with galvanometer?
A galvanometer is a simple meter that detects the flow of current. A current flowing in a wire causes magnetism around the wire. This is called electromagnetism. Like poles of a magnet repel and opposites attract. The Galvanometer uses these principles in order to move a pointer across a scale.
A moving coil galvanometer can be used as an ammeter by adding?
a series resistence with its coil

How do you get Ballistic Knife in COD MW3 and BO?
In MW3, it is unlocked at Level 80, and in BO; it is unlocked at Level 12 and costs 2000 COD Points
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 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 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?
Why you put coil in nonmetallic frame not in metallic frame in ballistic galvanometer?
A nonmetallic frame is used for a ballistic galvanometer to prevent damping of the coil movement by eddy currents induced in a metallic frame. This allows the coil to move freely and respond accurately to the changing magnetic field, making the instrument more sensitive and accurate in measuring current pulses.
While transporting sensitive galvanometer the terminals are?
connecting the damping resistance across the terminals
What is ballistic galvanometer.Give the construction and theory of moving coil ballistic galvanometer.?
a ballistic galvanometer is a specially designed galvanometer suitable for measuring the total quantity of electricity or charge displaced by a varying current of short duration such as charging & discharging of a capacitor >>>>
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 Construction of moving coil ballistic galvanometer?
A moving coil ballistic galvanometer is a sensitive instrument used to measure small amounts of electric charge. It consists of a coil of wire suspended between two pole pieces of a permanent magnet. When a current passes through the coil, it experiences a torque and deflects, allowing the measurement of charge.
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 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.
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.
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.
