s chapter. DYNAMIC ELECTRICITY. 443 or as 5 to 4. The E. M. F. of the battery measured is there-fore 0-8632 volt. A convenient arrangement of the tangent galvanometerscale is to have one side of the scale divided into degrees,the other side being arranged according to the tangentprinciple, so that… … Diagram of Wheatstones Bridge. sistance and a galvanometer are placed in the circuit of thebattery. The deflection of the galvanometer needle is noted.A variable known resistance is then substituted for the un-known resistance, and adjusted until the deflection is thesame as in the first case. The…
