The conserved current is the electric current.

It has the middle leg moving in synchrony with the front, and the hind leg on the other side. Sort of an alternating tripod, and they can negotiate obstacles just like the animal.

Moreover, no one party or figure has dominated French politics for too long, with power alternating regularly between parties of the left and the right, at least since François Mitterrand s first victory in 1981.

Simultaneously, the Muslim Brotherhood tried to step up their game, and announced that Khairat Al Shater, former deputy supreme guide of the Muslim Brotherhood and businessman tycoon, is their choice in Egypt's alternating Presidency act.

Conversely, if the current through an ideal current source is determined by some other voltage or current in a circuit, it is called a dependent or controlled current source.

They are also popular among traditional climbers, and particularly in the UK, due to the ability to clip each rope into alternating pieces of protection allowing the ropes to stay straighter and hence reduce rope drag.
