... To turn off the current source, we make the current equal to 0. We need to make it an open circuit here so the current is 0. To turn off the voltage source, we need to make it a short circuit. Look at the two 10 kΩ resistors. They are in parallel because they share the same pair of nodes. The two 10 ...

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.
