... estimation shows that the bipolar power supply might draw as much as 60 watts. This suggests a total current drain of 0.5A (60W divided by 120V). To avoid blowing fuses repeatedly, and yet provide good protection from serious conditions, we’ll double this to arrive at a final suggested rating of 1A. ...

Current source
A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it.A current source is the dual of a voltage source. The term constant-current 'sink' is sometimes used for sources fed from a negative voltage supply. Figure 1 shows the schematic symbol for an ideal current source, driving a resistor load. There are two types - an independent current source (or sink) delivers a constant current. A dependent current source delivers a current which is proportional to some other voltage or current in the circuit.
