âA higher salary or wage that is a higher price in the labor market leads to a decrease in the quantity of labor demanded by employers. A lower salary or wage leads to an increase in the quantity of labor demanded. A higher price for labor leads to a higher quantity of labor supplied.
Electric Current. If the two requirements of an electric circuit are met, then charge will flow through the external circuit. It is said that there is a current-a flow of charge. Using the word current in this context is to simply use it to say that something is happening in the wires-charge is moving.
1 The most common manifestation of charge in motion is the movement of electrons in a wire such as the wire leading to the computer that is running this lesson. 2  That's one form of current. 3  Here's a simulation that lets you see how charge flows around an electrical circuit through several elements. Like water flowing in a pipe, current flows in a wire. 2  Just as the water in the pipe is confined to the pipe, the charge flowing in a wire is confined to the wire. 3  It can't get away, and stays within the wire surface. 4  Like water flowing in a pipe, charge has to go somewhere.
