Conversion of Galvanometer Manufacturer,Supplier and Exporter in India

Product Code : SCL-EAE-11201

The Conversion of Galvanometer apparatus supports the experimental study of electrical measuring instruments. During the ammeter-conversion experiment, a low-value shunt resistance is connected in parallel with the galvanometer. During the voltmeter-conversion experiment, a high-value resistance is connected in series with the galvanometer.

The setup helps students connect circuit theory with actual meter behaviour. Learners can study galvanometer resistance, figure of merit, current range, voltage range and resistance selection through supervised practical work. The exact meter range, resistance values, construction materials and supplied accessories must be confirmed from the final Lab Exports product specification.

Key Features

Two practical applications: Supports the study of galvanometer conversion into both an ammeter and a voltmeter.

Demonstrates shunt resistance: Shows how a low resistance connected in parallel extends the measurable current range.

Demonstrates series resistance: Shows how a high resistance connected in series enables voltage measurement.

Supports quantitative experiments: Allows students to calculate the required resistance using measured circuit values.

Suitable for teaching laboratories: Relevant to secondary-school, senior-secondary, college and introductory engineering practical work.

Reinforces circuit connections: Helps learners distinguish correctly between parallel ammeter connections and series voltmeter connections.

Reusable laboratory apparatus: Intended for repeated demonstrations and practical sessions when operated within its verified ratings.

How to Use the Conversion of Galvanometer Apparatus

Identify the galvanometer terminals, resistance components and intended experiment range.

Determine the galvanometer resistance and full-scale deflection current using the prescribed laboratory method.

For ammeter conversion, calculate the required shunt resistance and connect it in parallel with the galvanometer.

Connect the converted ammeter in series with the test circuit.

For voltmeter conversion, calculate the required high resistance and connect it in series with the galvanometer.

Connect the converted voltmeter in parallel across the circuit element being tested.

Apply power gradually and compare the observed readings with a reference meter where available.

Record the readings, calculations, percentage error and experimental observations.

Safety note: Switch off the power supply before changing connections. Confirm polarity, begin with the lowest safe current and never exceed the verified galvanometer or resistor ratings.

Care & Maintenance

Keep the galvanometer disconnected when the apparatus is not in use.

Store the equipment in a dry cabinet away from dust, moisture and strong magnetic fields.

Avoid mechanical shock and do not force the meter pointer or adjustment control.

Inspect leads, terminals and resistance components before each practical session.

Frequently Asked Questions

What is the Conversion of Galvanometer apparatus used for?

It is used to study how a galvanometer can function as an ammeter or voltmeter after adding a correctly calculated resistance.

How is a galvanometer converted into an ammeter?

A low-value shunt resistance is connected in parallel with the galvanometer. Most of the measured current passes through the shunt, protecting the galvanometer coil and extending the current range.

How is a galvanometer converted into a voltmeter?

A high resistance is connected in series with the galvanometer. The resistance limits current through the coil and enables measurement of a specified potential difference.

Why is an ammeter connected in series?

An ammeter is connected in series so the circuit current passes through it. A converted ammeter should have low effective resistance to minimise disturbance to the circuit.

Why is a voltmeter connected in parallel?

A voltmeter is connected across a component to measure potential difference. Its effective resistance should be high so that it draws minimal current from the circuit.

Is this apparatus suitable for school laboratories?

Yes. It is suitable for supervised senior-secondary, college and introductory technical laboratory work when the supplied ranges match the prescribed experiment.
