Jump to Question: Fill in the blanks below: The flow of electricty is similar to the movement of water through a pipe. The movem
ent is the __________, the force of the current is the __________, and the rate of the current is the __________. For electricy to move it requires a complete __________ so the electricty can flow both in and out.
Water moving through pipes is like electricity flowing in a circuit. The flow of electricity is an actual flow of electrons. That movement of electrons is what is known as current. Think of current as the volume of water flowing through a water pipe. The electrons need some force or pressure to move, and so is water in a pipe. The voltage is that electromotive force; the pressure that pushes the electrons in a system. The power measured in Watts is the rate at which the energy is consumed. For the current to flow the circuit must be complete. Otherwise we cannot say that we have power if the circuit is not closed.
