Define Current And Voltage Sensitivity Of A Galvanometer
Define Current And Voltage Sensitivity Of A Galvanometer. It is defined on the deflection of coil per unit potential difference across its ends. The deflection θ per unit current i is known as current sensitivity θ/i.

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. Define current sensitivity and voltage sensitivity of a moving coil galvanometer. It is an appliance for detecting and measuring electric current.
A Galvanometer Is Said To Be Sensitive If It Produces Large Deflection For A Small Current.
(b) a galvanometer has resistance and shows full scale deflection for current. Videos you watch may be added to the tv's watch. The relation between voltage sensitivity σ v and the current sensitivity σ i of a moving coil galvanometer is (given that g is the resistance of the galvanometer)
It Is Defined On The Deflection Of Coil Per Unit Potential Difference Across Its Ends.
Current sensitivity is defined as the ratio of deflection produced in the galvanometer to the current flowing through it. Galvanometer is used to detect current in a circuit. The deflection θ per unit current i is known as current sensitivity θ/i.
Sensitivity Is Of Two Types, Namely Current Sensitivity And Voltage Sensitivity.
Current sensitivity,
the si unit of current sensitivity is. Sensitivity will be large if for small value of current (i) q in large. (ii) what is the effective resistance of this ammeter ?
Current Sensitivity Determines How Much A Galvanometer Will Deflect On Passing Some Current Through It.
No current flows through the galvanometer for balanced wheatstone bridge. A galvanometer is a type of ammeter. Similarly, voltage sensitivity determines how much the galvanometer will undergo deflection when some potential difference is applied across its ends.
So, The Voltage Sensitivity Of A Galvanometer Is Defined As The Deflection Per Unit Voltage Across The Galvanometer.
The current sensitivity of the galvanometer is defined as the ratio of deflection produced in the galvanometer to the current flowing through it. The current sensitivity of a galvanometer is the deflection per unit flow of current. Increasing the current sensitivity may not necessarily increase the voltage sensitivity of a galvanometer.
