Abstract: The invention is directed to a current regulator for an electromagnetic load used in conjunction with an internal combustion engine. The regulator produces positive and/or negative currents flowing through an electromagnetic load. In this arrangement, the two potentials present at a precision resistor that is connected in series with the load are adjusted to freely selectable values. To obtain both positive and negative currents, the current defined by the voltage drop occurring along the precision resistor is provided by a bridge circuit made up of four current-controlling arrangements. Allowance can be made for particular operating conditions of the current regulator simply by presetting desired values.
