Instructions : Drag and drop a material into the drop area (dashed grey box) and find out if it is a conductor or insulator.
What is Electricity or Electric Current?
Electricity is the steady flow of charges. In a closed circuit, the continuous flow of negatively charged electrons through conductive material such as metallic wire is known as electric current.
What is a Conductor?
A conductor is a material that allows easy flow of electric current when a voltage is applied across it. Examples - silver, copper, gold, aluminum, graphite, seawater.
What is an Insulator?
An insulator is a material that inhibits the flow of electric current. Examples - plastic, glass, rubber, wood, distilled water.
What is a Circuit?
A circuit is a closed path through which electric current flows. It usually has a source of electricity, such as a battery, a conducting path made of wires, and other components such as a switch and a load.
Basic Parts of a Circuit -
- Conducting Path - The wires that carry electric charge from the power source to the load.
- Power Source - An electric cell or battery that provides electric power to the load.
- Load - An electric component that consumes electric power. Examples - light bulb, computer, television, fan.
