About Ballistic Galvanometer

Ballistic Galvanometer

For measurement of small quantities of electrical charge. the moving coil is suspended by a phosphor bronze strip, which carries an optically true concave mirror. The coil can be raised, lowered or set to zero by an adjusting knurled knob at top. A knob at back is provided for clamping and releasing the coil. With levelling screws.

Technical Specification

Sensitivity of coil 100 ohms 10-12 sec. 180 mm

Resistance Period Sensitivity of coil 500 ohms 10-12 sec. 400 mm

Exceptional Sensitivity for Accurate Measurement

Engineered for high sensitivity, this ballistic galvanometer is suitable for detecting small currents and charges as low as 200 micro coulombs. Its low internal resistance minimizes measurement errors, enabling precise data collectiona key requirement in quality laboratory experiments and research.

User-Friendly and Durable Design

The galvanometer is designed with user convenience in mind: screw terminals simplify wire connection, while the external zero adjust knob and aperiodic damping ensure quick, stable readings. Its sturdy metal construction with a glass cover, along with anti-slip feet, provides long-lasting durability and operating stability.

Versatile Laboratory and Research Instrument

Optimized for physics laboratories, educational demonstrations, and scientific research, this analog device does not require external power. It remains an ideal choice for manually measuring electric charge and current, supporting clear experimentation and demonstration requirements in indoor scientific environments.

FAQs of Ballistic Galvanometer:

Q: How does the high sensitivity of this ballistic galvanometer benefit small current detection?

A: The high sensitivity allows it to detect and measure extremely small electric currents and charges. This precision is essential in laboratory experiments and research where detecting subtle changes is crucial for accurate results.

Q: What is the process for connecting wires to this galvanometer?

A: You can easily connect wires using the screw terminals provided. This design allows for secure, reliable wire connections, reducing setup time and ensuring stable measurements during use.

Q: When is the external zero adjust knob used?

A: The external zero adjust knob is used before taking measurements to set the pointer precisely at the zero mark. This ensures high measurement accuracy, compensating for any pointer drift that may have occurred during previous usage or transportation.

Q: Where is this ballistic galvanometer commonly used?

A: This galvanometer is widely utilized in physics laboratories, educational institutions, and scientific research facilities across India and internationally. Its reliable design and precise readings make it suitable for demonstrative and investigative purposes.

Q: What advantages does the aperiodic damping system provide?

A: Aperiodic damping prevents the pointer from oscillating excessively, enabling it to settle quickly at the correct value. This allows you to obtain accurate readings in a shorter time, boosting efficiency during measurements.

Q: How does the included mirror strip help achieve accurate readings?

A: The mirror strip beneath the pointer helps users avoid parallax errors by aligning the pointer reflection with the scale, ensuring that readings are taken from the correct angle, thereby enhancing measurement accuracy.
