You have given each bulb its own circuit. Observe what happens when you unscrew one bulb in a series circuit. Suppose you had a string of patio or Christmas tree lights plugged in and one bulb burned out. Name at least one advantage and one disadvantage of electrical wiring done in parallel and done in series. What's Happening Electricity is a form of energy that comes from the movement of electrons .
Electrons are tiny particles in any atom .
Since electrons are negatively charged particles, they are attracted to positively charged objects and are repelled by negatively charged objects, including other electrons. Movement of electrons creates an electrical current . The unbroken path or loop through which electricity flows is called a complete or closed circuit . If the electricity does not flow at all, then we know there is a break in the circuit, or an open circuit . When you turn on a switch, the break is closed and the electric current can now travel through the wire to a light a bulb, buzzer a buzzer, or turn a fan.
