Here we have some circuits with voltage sources.
... In the third circuit, each voltage source can establish its specified voltage across its terminals, so this is fine. In the next circuit, one source puts 1 V across the resistor while the other source puts 2 V across the resistor. This is not possible. We can’t have two different voltages across the ...

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.
