Why Do Bulbs Need Insulators? Conductors and insulators are also important components in electric circuits. Conductors (usually metals) are materials that allow electricity to pass through them. … If added to a circuit, insulators will stop the flow of electricity causing the bulb not to light. Why is an insulator important? Insulators are important to
What Charges Can Move Easily? A negative electrical charge is an electron. A neutron has no charge. Negative charges can move freely from one object to another. What materials allows charges to flow easily? Metals such as copper and silver are good electrical conductors. Wood, plastic, rubber, and air are good electrical insulators. An electrical
What Is A Continuous Conducting Path? A continuous conducting path consisting of wires and other resistances (like electric bulb, etc.) and a switch, between the two terminals of a cell or a battery along which an electric current flows, is called a circuit. It is a continuous and closed loop or path of electric current.
