Question
Chapter 31, Problem 1PLA
To determine
The principle on which the operation of a D’Arsonal type galvanometer is based.
Expert Solution & Answer
Answer to Problem 1PLA
The operation of a D’Arsonal type galvanometer is based on the principle that wire coil placed in a magnetic field would experience a torque when the current is applied.
Explanation of Solution
D’Arsonal type galvanometer can be calibrated to work as ammeter or voltmeter. And its mechanism is mainly based on the
The principle of D’Arsonal type galvanometer is based on the fact that wire coil placed in a magnetic field would experience a torque when the current is applied. Then the torque is exerted against a spring.
Therefore, the deflection of the needle attached to the coil in the galvanometer is proportional to the current in the coil.
Conclusion:
Thus, the operation of a D’Arsonal type galvanometer is based on the principle that wire coil placed in a magnetic field would experience a torque when the current is applied.
