\, 10, 100,1000, etc., the effect of the shunt may he conveniently varied. Fig. 79shows the arrangement sometimes adopted in the Ayr ton and Mathershunt: G and G are connected to the galvanometer and L L are thecircuit terminals. With the rotat-ing arm as shown, the value of theshunt is -i,. It… … Fig. 79. and the main current may be thereby altered. For the main currentto be unchanged, these values of the resistance must be the same, G = G-f-R - R ., or, R = hG. Thus for any given value of the shunt, say ^-, the effective resistanceof the circuit is unchanged on employing the shunt,…
