What is electricity?
Electricity is a movement of small charged particles inside of electrical wires. As particles move, so does energy. We need energy to power up electrical devises to make them work.
How fast does electricity flow?
Scientists say that electricity in wires flows very slowly. The speed of electricity depends on the size of the wire and the value of the electric current.The speed of flow of electrons in metal wires is slow. A HIGH current is simply a FAST flow of "electricity."
Interesting paradox.
Even though electricity flows quite slowly, wires can deliver energy almost instantly. No charges are gained or lost during this process, electricity is NOT consumed or used up in an electric appliance. Neither is it created. Instead, the electricity behaves like a mechanical drive-belt: it fills the whole circuit, and it moves along slowly, yet it can deliver energy instantly to all parts of the circuit or "belt."
How do we measure electricity?
Electric flow is measured in Kilo (1000) Watts (power) per hour. You electric bill usually shows you how much power you used per hour for the last month. The monthly energy consumption of a typical residential customer ranges from a few hundred to a few thousand kilowatt hours.
