It is unable due to a lower value of c.
- When the current travels through the active circuit and the suspension wire is thin, the null pointer of galvanometer vibrates.
- It vibrates about its ordinary position due to the tiny value of c and the considerable values of a, b and n.
- After moving for a while, it comes to a halt. As a direct result of the tiny value of c and the enormous moment of inertia, it is not stable.
