Si Unit Of Voltage Sensitivity Of Galvanometer

Si Unit Of Voltage Sensitivity Of Galvanometer. The voltage sensitivity of the galvanometer is defined as the deflection produced in the galvanometer when a unit voltage is applied across the terminals of the galvanometer. S i = i θ si unit of current sensitivity si is division/ampere or radian /ampere.

The deflection of galvanometer per unit voltage is called voltage sensitivity of a galvanometer.

S I = I Θ Si Unit Of Current Sensitivity Si Is Division/Ampere Or Radian /Ampere.


Current sensitivity of a moving coil galvanometer is 5div/ma and its voltage sensitivity (angular deflection per unit voltage applied) is 20div/v. What is the resistance of the galvanometer? Sensitivity of galvanometer is defined as the current in micro ampere required to consume one millimeter deflection on a scale placed 1m away from the mirror.

Current Sensitivity Is Defined As The Ratio Of Deflection Produced In The Galvanometer To The Current Flowing Through It.


So, voltage sensitivity = θ/v = θ/ig =. The resistance of the coil of the galvanometer is called the resistance of the galvanometer. So, voltage sensitivity of a galvanometer can be increased by increasing the value of b, n and a.

Voltage Sensitivity Of A Galvanometer Is Defined As The Deflection Produced In The Galvanometer When A Unit Voltage Is Applied Across Two Terminals.


Current sensitivity of a moving coil galvanometer is 5 div\/ma and its voltage sensitivity (angular deflection per unit voltage applied) is 20 div\/v. Similarly voltage sensitivity is defined as deflection per unit volt. Voltage sensitivity of the galvanometer:

From equation (1) and (2) sv = (b*n*a)/r*k. So, the voltage sensitivity of a galvanometer is defined as the deflection per unit voltage across the galvanometer. What is the si unit of galvanometer?

To Increase Sensitivity Of Galvanometer


I s = θ/i = nba/c. Figure of merit of a galvanometer is the reciprocal of current sensitivity. Why is ammeter is connected in series?
