Q. How can we increase the current sensitivity of a galvanometer?
The current sensitivity of a galvanometer is able to be increased by
(i) Rising the number of turns
(ii) Rising the magnetic induction
(iii) Rising the area of the coil
(iv) Declining the couple per unit twist of the suspension wire.
Is it possible to construct a vibration magnetometer at home?? If yes then what all materials will i require ? Also what is the working principle of the vibration magnetometer?
Two travelling sinusoidal waves are described by the wave functions Y 1 = 55.00 sin [π (4.00 x - 1200 t )] Y 2 =55.00 sin [π (4.00 x - 1200 t - 0.250)] Where x ,
Are the side emitting fibers with reflecting core more luminous? To answer this honestly is very much as trying to find out the sex of the angels. When a side emitting light gu
When a pulse is reflected from a free side, then there is no changing of medium. Crest (C) represents as crest (C) and trough (T) denotes as trough (T), Time changes by zero and
1. The probability of dissociation of water into H + and OH - , to a good approximation, can be characterized by the Boltzmann distribution: W ≈ e -Eα/ KT If, at 27°C, 1.
