to get critical damped system
In the damping level the level view and vertical spindle are crossed together...
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.

In MW3, it is unlocked at Level 80, and in BO; it is unlocked at Level 12 and costs 2000 COD Points
What is the difference between the construction of a moving coil galvanometer and a 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 >>>>

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.
An unstable galvanometer refers to a type of galvanometer that tends to oscillate or exhibit excessive sensitivity, making it difficult to maintain a steady position when subjected to external influences. This instability can arise from factors such as mechanical design, insufficient damping, or sensitivity to external magnetic fields.

Small amounts of current
when current passes through a coil of b.g then it rotates in a magnetic field and measures the quantity of charge rather than current
i think this is galvanometer so galvanometer is a device which detect the current as well as it measure small amount of current
GALVANOMETER detects very small currents in terms of milli amperes so it is said to be called as sensitive
A galvanometer is used to measure small currents.
