Shunts for varying the sensitivity of a

**galvanometer**are frequently made in thedial-switch form also, but the resistance steps are unequal. The Ayrton type of

**galvanometer**shunt is illustrated schematically in Fig. 4.14. Let R be the totalvalue of ...

the square root of the

**galvanometer**resistance (Sec. 10.5). Thus, writing d for thedeflection, d = CVR, i, where C is approximately a constant for a given

**galvanometer**design. From this it is evident that the square of the deflection isproportional ...

A very sensitive

**galvanometer**of this type will give a deflection of 1 mm. on ascale 1 m. away for a current of about 10-" amp., i.e., S = 10−". It will be seen later

that a

**galvanometer**of small internal resistance is most efficient for detectingsmall ...
