set up the bridge, theresistances made up should be carefully tested by placing them ingap a at X, and balancing against the standard i ohm coil. In thelarge resistance measure each coil separately and mark upon itsresistance, and with the zigzag resistance measure each step andmark its value.… … Metre Bridge wire of few turns, and consists of forty turns of No. 15 cotton-coveredcopper wire on a wooden bobbin, shown half-size in the illustration. To calibrate this ammeter we use the voltmeter and the resist-ances on the principles of Ohms laws. If we know any two of thefactors E, R, and C,…
