Top circuit is constant current.
Bottom circuit is constant voltage.

The circuits are identical..... the results are same (current and difference of potential on load).................

Yep, I agree. The 2 circuits are functionally equivalent. I'm currently working on a circuit that may help show the difference between voltage and current sources...

If you look closely, a constant voltage is present before the resistor. The other has a constant current after the resistor. This is a example of voltage vs current.

Please refer to this circuit for a working example of negative side control vs positive side control using the same parts same type of circuit just used in a different way. Same thing as a wiper delay circuit. Same parts in a slightly different configuration. https://everycircuit.com/circuit/4935576079564800

Check the movie flash of genius, if you don't understand the wiper delay reference.
