Parallel Circuits - Goodheart
... So far we have assumed that R1 equals R2. This is not always so. Often they are unequal, and there is not an equal division of currents flowing in the branches of the parallel circuit. In Figure 7-5, when the current reaches point X, it will still divide, but the greater amount of current will flow ...

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.
