What is electric current?
Electric current is an on going flow of electric charges through a material.

what is current in a circuit? (Also called an electric circuit)
An electric circuit is a complete, unbroken path through which electric charges can flow.

What are conductors and insulators?
A conductor is a material through which charge can flow easily. Insulator is a material through which charges cannot flow easily.

What is voltage?
The difference in an electric potential energy between two places in a circuit.

What is resistance?
Resistance is the measure of how hard the electric charges that can go through the material

What is insulators used for?
Insulators are used to stop the flow of charge.
300
The inner wire is the conductor for the current. The rubber coating around the wire is the insulator.
Why don't you get a shock from touching an extension cord?

Why don't you get a shock from touching an extension cord?
The inner wire is the conductor for the current. The rubber coating around the wire is the insulator. The cord allows charge to continue to flow to the appliance, but stops it from flowing into your hands and shocking you.
