Tangent galvanometer meaning

Tangent galvanometer definitions

When it comes to measuring electric currents, a tangent galvanometer is an essential tool that has been used for many years. This instrument was invented by German mathematician and physicist Johann Christian Poggendorff in 1825.

Tangent galvanometers work based on the principle of measuring the angle of deflection produced in a magnetic needle when a current passes through a coil. The tangent of this angle is directly proportional to the strength of the current flowing through the coil. This relationship allows for accurate measurement of electric currents.

Components of a Tangent Galvanometer

The main components of a tangent galvanometer include a coil of wire, a magnetic needle mounted at the center of the coil, a circular scale around the coil to measure the angle of deflection, and a mirror attached to the magnetic needle to read the scale accurately.

Working Principle

When a current is passed through the coil, it creates a magnetic field that interacts with the magnetic needle, causing it to deflect. The angle of deflection is measured using the circular scale, and the tangent of this angle provides a direct measure of the electric current flowing through the coil.

Tangent galvanometers are known for their high accuracy in measuring small currents. They are often used in educational settings for physics experiments and demonstrations due to their simplicity and precision in measuring electric currents.

Applications

Tangent galvanometers have been widely used in physics laboratories for educational purposes and for calibrating other electrical instruments. They are also used in research settings where precise measurements of electric currents are required.

In conclusion, the tangent galvanometer is a fundamental instrument for measuring electric currents accurately. Its simple yet effective design allows for reliable measurements in various settings, making it a valuable tool in the field of electrical measurements.
