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..
