This instrument comes in ballistic, conventional and D'Arsonval varieties.
This instrument comes in ballistic, conventional and D'Arsonval varieties. Any conventional type may be employed as a ballistic type, but the latter has smaller torque and higher inertia in the coil. The torque on the moving coil rotates a needle to measure the current running through the coil. FTP, name this instrument used to measure a small amount of electrical current of any function of that current.
