Every material conducts electricity, some materials are just better than others. The best conducter of electricity is silver, but silver is very expensive. Because of this, copper is used as it is a very good conductor of electricity but it is cheap.

Explain how a simple motor functions?
it converts electrical energy into mechanical energy
A kilowatt-hour is a unit that measures?
Quantity of electrical energy.
How do lighting rods proctect structures?
By grounding electrical energy.
What term for the difference in electrical energy between 2 places in a circuit?
Voltage.
What does hydoelectric power mean?
You probably mean "hydroelectric power". It basically means the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most used form of renewable energy.
A material that heat or electrical energy can pass through easily?
consendation
What a intervening substance that allows energy to pass?
That depends A LOT on the type of energy. For example, light energy will pass through transparent substances, such as glass; electrical energy (in the form of a current) will pass through conductors, especially metals, etc.
How are condutors and insulators different?
A conductor is any material that allows an electric current to pass through easily and an insulator is a material that stops or slows energy
How does electrical energy travel?
Through electrical wires.
Electrical energy is the energy of what?
Electrical energy is the energy made available by the flow of electric charge through a conductor.
What material stops the flow of electrical current?
Light energy
What is the function of an electrical circuit?
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
What items are conductors?
A conductor is simply a material that allows electrical energy to pass through it these tend to be metals or molten metal ions.
A type of battery that changes chemical energy to electrical energy in a nonliquid material?
dry cell
What type of energy can be moved through conductors?
electrical
Why is less resistance for a conductor wire good?
Resistance in a wire restricts the movement of the electrons through the wire. This restriction transfers some of the energy contained in the electrons into the material of the wire and as this energy accumulates in the material of the wire the wire starts to heat. Therefore, there the energy that is transferred into the wire material is considered wasted because it is not available as electrical energy, which means the consumer who is using that wire is charge for the electrical energy that is waste. It the resistance is less in that conductor the consumer will save money.
What device convert heat energy into electrical energy?
It is a thermocouple that converts thermal energy into electrical energy through what is called the thermoelectric effect.
