Ballistic Galvanometer Description and Specifications for Lab Tenders
Ballistic Galvanometer.
Ballistic Galvanometer Science Labs
a) Ballistic Galvnometer :-
Introduced very new type of
ballistic Galvanometer. The box & base are made of Aluminum. A large
coil wound on nonmagnetic & non-conducting material is suspended by
a phosphor bronze wire in pole piece of a very strong permanent magnet.
It carries an optical True concave mirror of about 1 cm. dia, A zero
adjuster is provided at the top. The coil can be damped by a lever when
not in use. The whole Front panel is covered by glass plate so teacher
can demonstrate each & every thing in the ballistic galvanometer to
the students.
The time period of moving coil is 10 to 12 seconds.
a. 100 ohms
b. 500 ohms
b) Ballistic Galvanometer :-
OSAW type coil resistance 100 ohms 0.3 Micro Amp. Senstive per division.
