Instantaneous Deflecting Torque

Go Instantaneous Deflecting Torque = Resistance*Spring Constant*(Current 1^2-Current 2^2)

Average Current through Galvanometer

Go Electric Current = (2*Coil Turns*Magnetic Flux)/(Time*Resistance)

EMF across Galvanometer

Go Voltage across Galvanometer = Resistance*(Current 1-Current 2)

Throw of Galvanometer

Go Galvanometer Throw = Ballistic Sensitivity*Charge

Constant of Galvanometer Formula

Galvanometer Constant = Charge/Galvanometer Throw
K_g = Q/θ

What is the working principle of Galvanometer

When an electric current passes through the coil, it generates a magnetic field that interacts with the field of the permanent magnet. This interaction produces a torque on the coil, causing it to rotate. The rotation moves the attached pointer across the scale, allowing the current to be measured. The amount of rotation (and thus the pointer deflection) is proportional to the current passing through the coil.

How to Calculate Constant of Galvanometer?

Constant of Galvanometer calculator uses Galvanometer Constant = Charge/Galvanometer Throw to calculate the Galvanometer Constant, The Constant of Galvanometer formula is defined as the measure of the sensitivity of the device. It represents the amount of current required to produce a specific deflection of the needle or coil. Galvanometer Constant is denoted by K_g symbol.
