    Study Notes

    Electrical Circuits and Safety

    • The main function of a circuit breaker is to protect an electrical circuit from damage caused by overcurrent or short circuit.

    Grounding and Polarization

    • A common ground in an electrical system ensures that all equipment is connected to the earth, providing a safe path for electricity to flow in case of a fault.
    • A grounding pole in a plug sends extra power away from a device, ensuring safety.
    • A polarized plug has one prong larger than the other, ensuring correct polarity and preventing electrical shock.

    Conductors and Circuits

    • A hot conductor is a wire that carries current from the power source to the equipment in an electrical circuit.
    • A ground conductor connects equipment to the earth, providing a safe path for electricity to flow.

    Circuit Functionality

    • The primary function of an open circuit is to prevent electricity from flowing, usually for safety or maintenance purposes.

    Electrical Power

    • The unit of electrical power, equal to one amperage under the pressure of one volt, is the watt (W).

    Electrical Safety Devices

    • A circuit breaker is designed to protect an electrical circuit from damage caused by overcurrent or short circuit.
