    1. 1. Building an Electric Circuit
    2. 2. Building an Electric CircuitElectric Circuit: A controlled path anelectric current passes through.
    3. 3. Building an Electric CircuitElectrical Load: Anything that converts electrical energyinto another form of energy, such as sound, heat, or light.
    4. 4. Electrical Loadslight bulb resistor motor Symbols for loads
    5. 5. Building an Electric CircuitConnectors: Provide a path for electric current toflow to each part of the circuit.
    6. 6. ConnectorsThey are typically conductors wrapped with insulators.
    7. 7. ConnectorsSymbols for connectors
    8. 8. Building an Electric CircuitElectric Source: Where the electricity comes from.
    9. 9. Electric SourceNegative Positiveside side Symbols for sources
    10. 10. Building an Electric CircuitClosed Electric Circuit: The electrons are free toflow or move throughout the circuit (ON).
    11. 11. Building an Electric CircuitOpen Electric Circuit: The electrons can notmove through the circuit because of a gap (OFF).
    12. 12. Switchesopen (off) closed (on) Symbols for switches
