Ballistic Galvanometer
The Ballistic Galvanometer (Product Code: SLE/CH/90) is a sensitive moving-coil instrument built to measure the total electric charge carried by a short pulse of current, rather than a steady current. Its heavy, slowly swinging coil receives the whole pulse before it starts to move, so the size of its first swing, or throw, indicates the charge that has passed. Physics departments in colleges and senior schools use it for capacitor and electromagnetic induction experiments, and it belongs among the physics lab instruments in India that make these classic practicals possible. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.
Key Details
| Parameter | Detail |
|---|---|
| Type | Ballistic galvanometer (moving-coil instrument) |
| Purpose | Measuring the charge passed in a brief current pulse |
| Suitable for | Capacitor discharge, comparison of capacitances, flux measurement with a search coil |
| Users | College and senior-school physics laboratories |
| Range, sensitivity and dimensions | Confirmed on enquiry |
Typical Use
A typical practical charges a capacitor from a known voltage and then discharges it through the galvanometer: the throw is proportional to the stored charge, so repeating the test with a second capacitor lets students compare the two capacitances. With a search coil connected, the galvanometer records the charge induced when the coil is pulled out of a magnetic field, giving a measure of the magnetic flux. Other undergraduate experiments use it to study mutual inductance and to find very high resistances by the leakage method.
Set the galvanometer on a firm, level bench away from vibration and magnets, and let the coil come to rest before each reading. Record the first throw only, then use a short-circuit or damping key to stop the coil before the next test. Keep the coil clamped, or the terminals shorted, whenever the instrument is moved, as this protects the delicate suspension.
Manufacturer
This instrument is built by Jain Scientific Equipments Private Limited, which markets its range as ScienceLab from Ambala, Haryana, India. For company background, see the company profile.
Related Laboratory Equipment
Items commonly used in ballistic galvanometer experiments:
- Capacitor (Charging and Discharging) — the circuit whose discharge the galvanometer measures
- Search Coil — for measuring magnetic flux by induced charge
- Power Supply Variable — charges the capacitor to a set voltage
- Moving Coil Galvanometer — a standard galvanometer for steady-current work
- Galvanometer 50-0-50mV — a centre-zero meter for simpler induction demonstrations

Frequently Asked Questions
How is a ballistic galvanometer different from an ordinary galvanometer?
Its coil swings slowly, so it measures the total charge of a short current pulse from its first throw, while an ordinary galvanometer indicates a steady current.
What are its range and sensitivity?
These specifications are not in our current product listing. Please contact us for the datasheet before ordering.
Which accessories do I need?
Typically a capacitor, a DC source, a charge–discharge key and, for flux experiments, a search coil. Accessories are not listed as included, so confirm with us what will be supplied.
Is a calibration certificate available?
Discuss calibration certificate availability with us when you request a quotation.
What warranty applies?
Warranty terms are confirmed at quotation — ask us for current terms.
What should a college quotation request include?
Quantity, the experiments you plan to run, any accessories needed, and the delivery location in India or overseas.
