are all electric currents caused by a flow of electrons?

"An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma."

The first thing that shows up when you Google it!

Like a river current is the flow water of water molecules, electrical current is the flow of charged particles. Current is the flow of charged particles through a conducting medium, such as a wire. When we talk about electricity, the charged particles we're referring to are almost always electrons. You see, the atoms in a conducting material have lots of free electrons that float around from atom to atom and everywhere in between. The motion of these electrons is random, so there is no flow in any given direction. However, when we apply a voltage to the conductor, all of the free electrons will move in the same direction, creating a current. and To Improve App lock Security, You must also install Leo Privacy Guard 3.0 in your smart phone, with Stylish themes.

Flow of electrons does not cause electric current. Flow of electrons IS electric current.

"Are all electric currents caused by a flow of electrons?"

An electric current can be the flow of electrons in a conductor, can be the flow of electron "holes" (makes sense in "P" semiconductors), can be charged particles (electrons, protons, nuclei) in a beam, and the flow of ions in the electolyte of a battery.

No. Changing electric field (dE/dt) in a region also constitutes electric current because the effect including the magnetic effect is indistinguishable from that produced by moving electric charges.
