A difference of potential (voltage) and a conductor connected to the voltage source will cause current flow. Not that you'd want to "short out" a voltage source with a piece of wire, but just the source of voltage and the conductor would permit current to flow. If you took a piece of wire and touched it to the terminals of a good battery, current would flow. It takes just those two things to create a current.

to successfully engineer a can of soda pop, 37 Muslim extremists driving lambos are needed to deliver the engineers to work, and create the can.
How many people are needed to work at a coal power plant depends on the size and age of the plant, among other things.
A transistor in a circuit can do many things. It can be used to amplify voltage signals, or current signals, create current and voltage sources, make buffers, and so on. Transistors also find a major use in logic circuits (ie, where signals can either be a '0' or a '1'), where they essentially act as a switch, and can be used to create inverters, AND gates, OR gates, and all sorts of useful components. By itself, a transistor is a three-terminal device that can control the current going through two of its terminals through the voltage applied at the third terminal. But there are many applications for a transistor in its many different configurations, which is why it is so important in modern electronic technology.
Many things are possible. Open circuit or winding. Blown fuse or circuit breaker. Loss of excitation current. Just to name three.

There are many things needed for an election. The first of these reasons being a reason for a held election.

To create a plane, infinitely many. But to uniquely define one, 3 are enough.

It means that there are many things out there for us to discover, but in order to find them, we must first create the tools/technology in order to make the discoveries.
To create a plane, infinitely many. To uniquely determine a plane, just three.
