Learn about electricity circuits as you experiment with conductors and power sources in this fun, interactive activity. Find out what materials conduct electricity better than others. Try lighting the bulb by putting different objects and materials such as a coin, cork, rubber, key, chalk, plastic or wire into the gap in the circuit.
Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air. The division of materials into the categories of conductors and insulators is a somewhat artificial division.
A conductor is anything that an electric current can pass through easily. Some examples of conductors include: most metals; salt water; lemon juice; Lightning is an electric current! As we know, electric currents try to find the fastest way to travel. In some cases, the fastest way for lightning to get from the sky to the earth is to strike ...

Copper (Cu) is a good heat conductor but has a high corrosion rate. Its color is reddish orange and has soft character with a boiling point of 2835 °K (2562 °C, 4643 °F). Therefore it is utilized for electrical conductor in the form of isolated cable. If it mixed with lead will produce bronze. Copper is usually used for medals.
Everyday Examples of Heat or Thermal Conduction. After a car is turned on, the engine becomes hot. The hood will become warm as heat is conducted from the engine to the hood. A radiator is a good example of conduction. Anything placed on the radiator, like an article of clothing, will become warm. You can warm your back muscles with a heating pad.

Examples of Insulating Materials: 1. Rubber. It is an insulating material that due to its composition is ideal for electrical installations, especially due to its dielectric qualities and ease of use in mechanical actions. It turns out to be a flexible handling material and presents a level of resistance that is difficult to break.
