Experimental evaluation of the current stabilizer

In control devices for various purposes it is frequently required that the given current in a load is supported without dependence on load resistance. For this purpose current stabilizers or amplifiers with current output are used, at which the target current changes proportionally to the source signal. Such circuits are necessary in devices whose resistance is proportional to some external effect. The amplifier circuits with current output permit, with large accuracy, the realization of Ohm´s law, if the resistance of load changes. In this case, the load voltage should be strictly proportional to its resistance
