Since the E. M. F. of the series dynamo increases with the current in the external circuit, while the E. M. F. of the shunt dynamo diminishes as the current in the external circuit increases, it is possible to wind both a series and a shunt coil on the same field magnets, and so to proportion them as to keep the E. M. F. practically constant at all loads. The compound dynamo is wound in this way and is the machine used for incandescent lighting.
