Understanding a Moving Coil Galvanometer and Its Deflection of 5 Degrees

What is a Moving Coil Galvanometer?

A moving coil galvanometer is a type of electrical instrument used to measure the electric current flowing through a circuit. It is also known as an ammeter. The instrument has a coil suspended in a magnetic field and a needle connected to the coil. The needle is attached to a calibrated scale and when current passes through the coil, it generates a magnetic field that causes the needle to deflect along the scale.

Why is a Moving Coil Galvanometer Used?

A moving coil galvanometer is used to measure the flow of electric current in a circuit. It is a very sensitive instrument, and can measure currents as low as a few microamperes. It is used in a variety of applications, such as testing electrical circuits, calibrating instruments, and for scientific research.

What is a Deflection of 5 Degrees?

The deflection of 5 degrees is a measure of the amount of current flowing through the coil. When the electric current passes through the coil, it generates a magnetic field which causes the needle to deflect along the scale. A deflection of 5 degrees indicates that the current is strong enough to move the needle 5 degrees along the scale.

How is a Deflection of 5 Degrees Measured?

A deflection of 5 degrees is measured by connecting the galvanometer to an electrical circuit and measuring the current flowing through the coil. The current is then compared to a standard scale, and the amount of deflection is calculated. The deflection is usually measured in millimeters or degrees.

Conclusion

A moving coil galvanometer is an electrical instrument used to measure the electric current flowing through a circuit. When the current passes through the coil, it generates a magnetic field which causes the needle to deflect along the scale. A deflection of 5 degrees indicates that the current is strong enough to move the needle 5 degrees along the scale. The deflection is usually measured in millimeters or degrees.
