PRACTICAL EXAM – 2024
THEORY
Galvanometer Resistance =
PROBLEM
A coil of diameter 2 cm and having 1000 turns is placed in a perpendicular magnetic field of 2 tesla. Find the angle through which one coil will turn when a current of 1 mA passes through it. [Take the twisting couple per unit angular twist of the suspension fibre, C = 10 power (-5) Nm/Rad]
