Question

8.
A moving coil Galvanometer coil is made of a coil of
radius 10 cm and 1000 turns. The strong horse shoe
magnet creates a magnetic field of 0.2 Tand spring
of spring constant of 0.5 N/m.
Find (a) Galvanometer constant.
(b)voltage sensitivity.​

Answer 1

Explanation:

when the current in Coimbatore starts flowing from 0 to maximum in a magnetic field around its changes with cause with which cause Galvanometer needle to deflect momentary a similar process occurs when the key is taken out and current goes down 0 to maximum which change is magnetic field and again cause a momentary deflection in the Galvanometer of coil
