inciples of Ohms laws. If we know any two of thefactors E, R, and C, we can find the third by calculation— So that we can make C any value we choose by adjusting E and R.Thus if we take one of the large cells giving E = 2 volts, and makeup a circuit consisting of the cell, the ammeter, and the… … Fig. 39.—Testing with the Metre Bridge series, and adjusting the resistance until we get it correct at2 ohms. As it is known the spirals are each about i ohm, we put two inthe circuit, and finally adjust with the zigzag board rVth at a time ; the wire reading- on the brido-e would scale ^^^ with…
