Best Answer

restoring torque is k theta

the value of k depends upon the nature of the material used for suspension strip

value of k is very small for quartz or phosphor bronze

so in galvanometer phosphor bronze wire is used.

Write the construction of a moving coil galvanometer?

A moving coil Galvanometer consists of a coil PQRS which is wound over a non metalic frame having soft iron core in the middle. This Coil Is suspended in b/w a powerful magnet poles N-S with the help of Phosphor Bronze wire. Concave mirror is fixed on d suspending thread upside the coil through which deflection can b noted by Lamp and Scale arrangement. The lower end of the coil is connected by hair spring.
