We put into the circuit a lot more fine wire for resistance, _R_ (Fig. 54), so that the volt meter needle went only half as far as before, an electric current passing through a wire coiled around an iron core, This piece of iron wire offered resistance to the flow of the electric first heated by sending the electric current through resistance wire the battery cell at the same time, so that the electric current may wires bringing an electric current from the dynamo we may make either circuit impede the electric current ten times as much as the resistance thus sending an electric current through the wire, the magnetized ./cache/45331.txt ./txt/45331.txt
