Thus, writing d for the

**deflection**, d = CVR, i, where C is approximately a constantfor a given galvanometer design. From this it is evident that the square of the

**deflection**is proportional to the joule heating in the galvanometer. The**deflection**...

The

**deflection**is observed by viewing a scale in the mirror carried by the coil orby the

**deflection**of a beam of light incident on this mirror. Since the restoringtorque of the fiber is small, the sensitivity of this type of instrument can be made
