Transcript of Conductors and Insolaters

Conductors and Insulators
In a conductor an electrical current can flow freely. In a Insulator it cannot. A conductor is a object or material that allows the flow of electrical current in one or more directions. A wire is an conductor because it allows electricity to flow through it. An insulator is an object whose center electric charges do not flow freely making it difficult to conduct an electric current. A possible insulator could be a piece of rubber.
A Circuit
A circuit has 3 main parts: a power source, a conducting path and a load, ( a load is something that will use the elctricity.) Example: a battery is a power source, a piece of wire is a conducting path and a light bulb/buzzer can be used for a load.
Series and Parallel Circuits
A parallel circuit is when each devices of a circuit have their own loop. A series circuit is a circuit that goes in a loop.
Thank you for wating!
A circuit is a root in which an electrical current can flow. Electrons flow from the negative side of a battery to a wire, then to a conductor. Electrons then will go to a wire inside a bulb and go across the filement, which is where the light comes from, some of the electrical energy changes into heat and light energy. Next, they go to another wire which leads them to another conductor, and finally to the positive side of a battery. This is called a complete circuit. A closed circuit is when the electrons follow a unbroken path.
