The precision current source is a wide spectrum, high-precision AC steady-current power supply, which has the advantages of fast response, high precision constant current, long-term stable operation, and is suitable for various types of loads (resistive, inductive, capacitive).
Since the current of the current source is fixed, the current source cannot be disconnected. When the current source is connected in series with a resistor, its effect on the external circuit is the same as that of a single current source. In addition, a current source and a voltage source can be equivalently converted, and a current source connected in parallel with a resistor can be equivalent to a voltage source connected in series with a resistor.
