The path that electricity travels in a never-ending loop is called an electric circuit. An electric circuit is very similar to the circulatory system of the human body. Just how blood continually flows around the body and coming back to where it originated, the electrons do the same thing in a circuit. Any circuit has four common components that make this possible. Conductors are the wire or metallic based substances that the electricity flows through. There is a small gap embedded in the conductor where you can close or open (turn on/off) the flow of electricity. The load is the object in the circuit that consumes the electric power, in most cases a light or electronic component. The power source that is making the follow of these electrons possible is called the cell which is often a battery.
These worksheets will help students examine electric circuits and how the materials they consist of effect the efficiency and flow of electrons within it. Students will explore the concept of conductors, resistors, and insulators. We will learn how you can determine the potential of a material based on the physical properties of what it is made up of. We will finish off by looking at how magnetism and electricity relate.
