Ballistic Galvanometer Manufacturer,Supplier and Exporter in India
Product Code : ILS-LM-10828
Indian Lab Suppliers supplies the Ballistic Galvanometer (Product ID: 10828) as part of its lab meters range. A ballistic galvanometer measures the charge carried by a short current pulse, for example when a capacitor discharges through it.
Quick Answer
Its long period of oscillation, 12 s, means the whole charge passes before the coil moves appreciably, so the first throw is proportional to the charge. The coil carries a mirror and hangs between a long upper suspension and a lower spring, both in a special alloy, with levelling screws and a Bakelite case. Two versions are offered: 100 Ω coil with 300 mm/µC and 1000 mm/µA, and 500 Ω coil with 600 mm/µC and 1400 mm/µA. Please confirm at quotation whether a lamp and scale arrangement is included.

Frequently Asked Questions
Why is the time period long?
So the charge passes before the coil moves, making the first throw proportional to charge.
What is the critical damping resistance?
2000 Ω for the 100 Ω coil and 3500 Ω for the 500 Ω coil.
Which version is more sensitive?
The 500 Ω coil: 600 mm/µC and 1400 mm/µA.
